ABSTRACT: A new method of photometric determination of titanium (IV) in
steel is proposed. The method is based on the formation of a
colored (yellow) complex by the reaction of titanium with salir
cylic acid and pyridine or other organic bases (quinoline) pyramidon),
The complex was separated and analyzed. It vas shown that it
contains the components in the following ratiot Pyridine:titanium:

It was assumed that the titanium:salicylic acid complex forms with
pyridine the following compound:

The ternary complex is only slightly soluble in water, but readily
soluble in chloroform. The optical density of the chloroform extract
of the tertiary complex is measured using SF-4 spectrophotometer.
Visually, 1 .10-5 g Ti/25 mls of the extract clan be determined.
The sensitivity of the proposed method is seven to eight times
greater than that of the hydrogen.peroxide method. Interference
of other elements is eliminated by complexing them with
thiosulfate. The following procedure is given. Dissolve the steel
sample in a mixture of sulfuric and nitric acids. Take an
aliquot of the solution and neutralize with ammonia to pH 1-2.
Add 1-2 drops of ammonium thiocyanate .. then add 10% tbiosulfate
solution dropwise until the iron-thiocyanate color disappears.

of the extract is measured at 1100-430 m ~, using the SF-4
spectrophotometer. Some standard steels were analyzed. The

TITLE: Spectrophotometric Analysis
PERIODICAL: Miimicheskaya, nauka i promyshlennost', 1959, Vol 4, Nr 2.
pp 164-171 (USSR)
ABSTRACT: Spectrophotometry has been developed on the base of colorimetry and
the absorption spectra of solutions. Colorimetry can be used only for
the visible part of the spectrum, spectrophotometric analysis includes
also the infrared and ultraviolet part. The ultraviolet spectrum is
especially useful in the analysis of fats, oils, vitamins, hormones,
etc Z-Ref 2-5_7. The molar coefficient of absorption E varies from
610 at the wave length 420 mu on the border of the visible spectrum
to 4,812 at 370 mjL in the field of maximum light absorption. It is
difficult to differentiate complex compounds by photometric methods.
For this purpose spectrophotometric analysis measures the light ab-
sorption at its maximum. If substances must be analyzed which have a
similar color, one of them must be transformed into a colorless compound,
so that analysis becomes possible. In many cases meaut:.rements at two
Card 1/3 different wave lengths permit the differentiation of two components in

the mixture. The Soviet spectrophotometers SF-2 and SF-4 operate in
the short-wave part of ultraviolet and are equipped with a hydrogen
lamp and quartz optical instruments. Light filters permit the use of
very sensitive photoelements. Such an apparatus is FEK-57j Vaich operates
nearly in the same part of the spectrum as SF-4, but is much cheaper.
rThe resolving power of an apparatus with light filters is lower than
that of the monochromatic devices, but is is sufficient for most prac-
tical purposes. Deviations in the measurements are caused by electro-
lytic dissociation of the colored complex. The deviation is consider-
able, if the numerical value of the concentration is approximate to the
numerical value of the dissociation constant of the complex group. The
proportionality between the general concentration and the optical density
is maintained, if the excess concentration of the reagent remains con -
stant during dilution. The transformation of colorless components into
colored compounds depends in many cases on the pH value of the solution.
The optical density is also affected by the temperature fRef 14-18j7.
The colored compounds used in spectrophotometric analysis are ions of
permanganate, chromate hydrated ions of copper, nickel, rhodanides of
various metals, like iron, cobalt, uranium, etc. Mary organic solvents,
e.g. acetone, are very important, especially in combination in'th the
Gard 2/3 rhodanides. Heteropolyacids, though still insufficiently investigated,

are used.in the determination of phosphorus, silicon, germanium, etc.
Uranium, titanium, vanadium, etc, are determined by the formation of
their peroxides or carbonate-peroxides. Acid dyes are used in the Ana-
lysis of beryllium, boron, aluminum, etc. For tin two special reagents,
stilbazo and hematoxylin have been d6veloped. New reagents with very
small absorption bands, different comFlex-forming groups and a molar
coefficient of light absorption of 10 and higher should be developed.

ABSTRACT: The production conditions of the titanium complexes with
oxalic acid in an acid medium were determined and the
composition and stability of these complexes investi-ated.
Physico-chemical methods were used foi- investigating the
oxalate-complex formation. The absorption spectra of the
titanyloxalic acid complex in the ultra-violet zone were
recorded and it was found that the absorption maximum is at
213-220 mg. The composition of the complex was determined at
a wave length of 213 miuby the method of isomolar series.
It was found that at pH < I titanium and oxalate ions form a
complex of the composition TiOC 204' Upon increase of the
pH value of the solution complex anions are formed, e. g.

ABSTRACT: The complex compounds of pontnvnlont molybdenum in hydro-
chloric acid solutions were investigated by spectrophoto-
metric determinations in the ultraviolet and visible range.
A reddish-brovn complex with the absorption maximum at
295 and 395 MRforms in < 2 n hydrochloric acid concentration.
With the increase in the concentration to 4-5 n a greenish-
brown complex forms with the absorption maximum at 450 and
730 mtt. At a further increase in the hydrochloric acid
concentration a greenish-blue complex forms with the absorp-
tion maximum at 240 and 310 m&. The absorption spectra of
molybdenum (V) were recorded at different hydrochloric acid
concentrations and are given by figures 1, 2, and 3. For
the explanation of the differences between the absorption
spectra and for the measurement of the optical density at
Card 1/4 A = 450 me ex-Deriments were carried out in series with
Chloride Complexes of Pentavalent Molybdenum SOV/78-4-3-16/34
molybdenum (V) solutions at constant concentration of hydro-
chloric acid (1.5 n) and variable concentration of lithium
chloride, as shown in figure 4. From these experiments it
follows that the complex formation is due to the variation
of the oxygen content in the coordination sphere. At constant
concentration of the hydrogen ions in the case of an increase
in the chlorine ionic concentration the second form of the
complex is formed and in the case of a further increase in
the[LiCl) -content to 6.5 n the complex passes over into
the third form. This transition of the complex is explained
by the introduction of the chlorine ion into the coordination
sphere. For the purpose of determining the composition of
the chloride complex of molybdenum (V) some isomolar series
of 140 V-LiCl were investigated in the presence of perchloric
acid. The experiments confirm that the absorption spectra
run parallel, measured in the range of the wave length of
350-500 M~A; they are also dependent on the acidity of the
solution. For the second complex form !JoOCl3 the ratio
Card 2/4 140V : Cl' = 1 : 3 was found. For the third form of the

ABSTRACT: For the purpose of determining the stability of the complexes
of various metal ions forming complexes with one and the same

MI and M II or by the corresponding volume of their solutions,
the relative stability of complexes MIA and MIIA can be
determined. By means of the new method it is possible to de-
termine the dissociation constant of the com.plexes. If the
same optical effect is attained, the following dependence
exists: M J'MII] : ... [Mn] - KMI, : K II ... : K_ _n

If the dissociation constant of one of theso complexes is
known, the dissociation constant of the other complex is de-
termined according to the aforementioned dependence. The ad-
vantages and disadvantages as well as the particular features
of this method are discussed. By means of this method it is
possible to determine the relative stability of numerous com-
plexes easily and rapidly. A previous determination of the
composition of complexes is not necessary. A disadvantage of
this method is the occurrence of secondary reactions.

ABSTRACT: The present paper gives results obtained by the application of
the metal-.indicator method (Ref 1) for the determination of the
relative stability of thQ fluorine complexes of some metals.
As indicator systems Fe.~'+-SCN_ and Ti -H2 02 were used. The
ferric thiocyanate indicator system was used in connection with
the following elements; Ga3+ I H BO Be2+, A*13+, Ta5+, Nb5+,
La3+ and T13+ (Table 1). Mode o~ ON
eration: In a 50 ml-measur-
ing flask 0-3 ml 0.1 molar solutions Pe(110 ) and a 5 ml 10%
ammonium thiocyanate solution were added. I~ Lese solutions
various quantities (of 0.5-4 ml) a 1-molar sodium fluoride
solution were added and adjusted to 50 ml with 0.2 '1 nitric
acid. The optical density of the solution was measured by means
of the spectrophotometer FM. Figure 1 shows the calibration
curve of the dependence of the optical density of the ferric
thiocyanate indicator system on the concentration of the sodium
Card 1/2 fluoride. The results obtained make it possible to determine

The indicator system Ti -11 02 is suited for the purpose of
investigating the more table fluorine complexes. The method
employed is similar to that of the ferric thiocyanate system.
Figure 2 shows the calibration curve for the dependence of the
optical density of the titanium-ferroxide indicator system on
the concentration of sodium fluoride. Elements forming weak
complexes, such as boron. cannot be investigated by means of
this system. For some complexes the approximate values of the
stability constant were determined and found to be in agr ement
with the values mentioned in publications (K,,,,2+ - 4-10-1 and

ABSTRACT: The dependence between the stability of the fluorine complexes
in aqueous solution and of the position'of the corresponding
central atoms in the periodic system was explained. The
stability of the fluorine complex in general increases with
a decrease of the ionic radius and with an increase of the
ionic charge. The first group of the peri,odic system contains
the insoluble fluoride of the lithium ion. In the second
group a stable fluorine complex of beryllium is formed. In
the third group the most stable complex is not that of boron
but that of aluminum. The stability of the fluorine complexes
in the third group develops in the following series:

ABSTRACT: The present paper gives a survey of the advantages and dis-

of tetravalent tin. Some hydroxyanthraquihones (alizarin,
quinizarin$ quinalizarin), quercetin, hematoxylin and stilbazo
were comparatively investigated by the spectrophotometric
method. It was found that the optical characteristics are
the most important criteria forthe suitablLity of these re-
agents. In the investigations the differences between the
absorption spectra of the H-form of the reagent and the
spectrum of the corresponding tin complex were used as
criteria for the sensitivity and accuracy of the determination.

Spectrophotometric Investigation of the Colored Complexes of Tetravalent
Tin With Some Reagents Containing OR Groups
Quercetin is still less sensitive, in the photometric deter-
mination it shows, however, the same advantages as hematoxylin.
Besides, quercetin is easily accessible. Fluctuations in the
DR value of the solution to be analyzed show the least ef-
fects in the use of quercetin for the photometric determina-
tion because the free reagent in the part of the spectrum in
which the absorption maximum of the tin complex is found does
not absorb at all. The color of the tin-quereetin complex
is stable at a pH - 3 - 6. The color of the tin-hematoxylin
complex also varies only little between pH - 2 and 6. The
properties for the determination of tin of the three dyes men-
tioned which are important are tabulated (pH values of appli-
cability, XM x of the absorption of thetLn complex, molar
absorption c8efficients of the reagent and the corresponding
complex).On the basis of the results obtained the optimum
conditions for the photometric determination of tin by quereetin,
bematoxylin and stilbazo are determined. These conditions are
described in detail in this paper. There are 6 figures, 1 table,
Card 3/4 and 12 references, 6 of which are Soviet.

ABSTRACT: The analy3es of materiale pertaining to the metallurgical
industry usually involve separation processes of either the
substance to be determined or of its impurities. In this con-
nection an ample survey of the pertinent methods is given.
The advantages offered by the extraction methods are described
as well as the factors influencing such extraction processes.
An enumeration of the inorganic complex compounds which may
be formed in such extractions is also given. The various
flucrides, chlorides, bromides, iodides, thiocyanates, nitrates
and heteropolyacids are mentioned and desc--ibed, and the
respective references are -indicated. Since organic solvents
are also often used in extraction processes, the respective
organo-metallic compounds are enumerated, among them the di-
phenyl-thio carbazonates, diethyl-dithio carbamates, ethyl

Development of Analytical Chemistry in the Year 1958
(Razviti.ye analiticheskoy khimii v 1958 9.)
PERIODICAL: Zavodskaya Laboratoriya, 1959, Vol 25, Nr 5, PY 515-534 (USSR)
ABSTRACTs The present paper gives a survey of the development of
analytical chemistry in 1958. The data, only a part of which
concerns the field of inorganic chemistry, are dealt with
in sections. In the case of new reactions made to determine
individual elements it is mentioned that for the most part
analyses were carried out on the basis of colored substances,
i. a. photometric methods were applied. A table is given
with new analytical reactions for about 35 cations (Table 1),
and another one (Table 2) with 12 reactions for nonmetals.
Another chapter deals with the deficiencies of investigations
in the field of the new reactions, as for example, the
insufficiency of data concerning the characteristics of the
respective reactions. Also the fact is mentioned that often
the requirements of analytical practice as well as the
necessity of elaborating theoretical problems are not
Card 1/2 complied with. Next, a comparison is made among various
Development of Analytical Chemistry in the Year 1958 SOV/32-25-5-1/56
analytical methods. The subject of pure metal analysis,
especially as concerns the determination of microimpurities
is dealt with, and reference is made to the compilation
"Trudy komisaii po analiticheskoy khimii" ("Transactions
of the Commission of Analytical Chemistry") Volume IX(XII).
The volumetric determination of metal cations is then
discussed, together with the photometric determination of
substances in larger quantities, the problem of automatizing
the production control, and finally, a few organizational
problems are mentioned, in which connection it is stated
that foreign periodicals often carry suggest4ons of various
modern laboratory equipments, while in the USSR this is
a too much neglected problem. It is also necessary to improve
scientific information, so as to keep the world informed on
scientific development in the USSR. There are 2 tables and
184 references, 84 of which are Soviet.

TITLE: Determination of Microimpurities in Zirconium by Means of
Basic Dyes
PERIODICAL: Zavodskaya laboratoriya, 1959, Vol 25, Nr 9, PP 1047-1050
(USSR)
ABSTRACT: For the enrichment of zinc, cadmium, molybdenum, and bismuth,
occurring as microimpurities in high-purity metallic zirconium,
a precipitation of the former may be carried out by means of
the basic dyes methyl blue (I) and crystal violet (II) in-the
presence of iodides (III) or thiocyanatea (IV). The resulting
precipitate may be separated by a flotation with the aid of
light, non-water mixable, liquids (toluene, ether). The im-
purities may then be determine?. Worimetrically from the
concentrate. The complateness of the zinc precipitation with
(10 and (IV) in the presence of larger zirconium quantities
65
was investigated by means of Z11 and it was found that
20 y Zn can be separated from 0-5 2.0 g Zr practically with-
Card 1/3 out loss, e.g. that 5-10- 5 - 1.10-5% Zn may be determined.
SOV/32-25-9-7/53
Determination of Microimpurities in Zirconium by Means of Basic Dyes
(II) besides (III) was used as precipitant for the concentra-
tion of cadmium. The analysis was carried out with Cd115.
30 Y Cd were separated from 0.5 - 4 g Zr with maximum losses of
5%i this method permits the determination of 1.10-5 _ 2.10-5% Cd
in 2 g of zirconium. The determination of the microquantities
of molybdenum in Zr was most favorable with (II) besides (IV);
it was also found that with Xo6+ a better precipitation can be
obtained than with Mo5+ (Table 1). A precipitation of Bi is
likewise obtained beat with (11) (according to Kuznetsov and
Panushina, Ref 6), as is shown by experiments with other dyes
((I) and rhodamine) (Table 2). An ammonium thiocyanate con-
centration of maximally 0.2 g.equivalent/1 should be used
(Table 3). According to the two methods mentioned last, quan-
tities of 5.10-5% Mo and Bi respectively, can be determined in
a 2 g weigh*ed portion, the precipitate separating, as above,
by flotation. There are 3 tables and 8 Soviet references.

TITLE: Investigation of the Reaction of Chromate With Diphenyl Carbazide
(Izucheniye reaktsii khromata s difenilkarbazidom)
PERIODICAL: Zhurnal obshchey khimii, 1959, Vol 29t Nr 7, pp 2416-2420 (USSR)
ABSTRACT: The formation of an intensely colored compound on the reaction of
chromateG with diphenyl carbazide (further designed as DO is
frequently used in the chemical analysis. Nevertheless, the
chemism of this reaction has hitherto been vigorously discus3ed.
Quite recently a number of new papers on this subject was
published. Without dealing with the details of these papers,
table 1 presents the principal data regarding methods and results
obtained by various scientists. It can be seen from it that the
data are contradictory. The investigations carried out by the
authors (Ref 5) with respect to the reaction of the trivalent
chromium with DCO in the presence of an acetate buffer solution
gave the following results: the trivalent chromium reacts
neither with diphenyl carbazide nor with diphanyl carbazone;
the bivalent one does not react with diphenyl carbazone. The
inaccurate data of a number of authors are explained by a side-
Card 1/3 process, i.e. by the formation of the above-mentioned compound

Diphenyl Carbazide
in the reaction of acetic acid with diphenyl carbaoone,
irrespective of presence or absence of chromium. In the reaction
of Cr VI with diphenyl carbazide a complex compound of the
trivalent chromium with the colored oxidation product of VI
diphenyl carbazide is formed. The colored reaction product of or
with diphenyl carbazide can be separated partially or nearly
completely, according to the conditions, from chromium by
extraction with isoamyl alcohol, in which connection the
absorption spectrum of the solution of the colored compound dooo
not vary. In thd presence of complex-forming compounds the
chromium combines with them without any loss of color of the
soluti.ons.In the presence of reduction a.c-ents added on reaction
of Cr N"I with diphenyl carbazide no colored compound is formed.
Some questions regarding the reaction mechanism of Cr VI with
diphenyl carbazide were discussed. There are 2 tables and
8 references, 2 of which axe Soviet.

SOURM Zhurnal neorganicheskiy khimii, v. lip no. 12, 1966, 2.835-2836
TOPIC TAGS; niobiump tantalum, hydrogen peroxide
ABSTRACT: A now method is proposed for extracting niobium and tantalum in which use
is made of sulfuric acid solutions containing hydrogen peroxide to dissolve niobium
nentoxide and tantalum pentoxide, no hydrofluoric acid being employed. With niobium
~nd tantalu:n, hydrogen peroxide forms cationic complexes which are extracted with acid
esters of phosphoric acids. At a sulfuric acid concentration of 1-3 moles/liter and a
hydrogen peroxide concentration exceeding the niobium and tantalum content by a: factor
of 2 to 8, niobium is extracted to the extent of 90-91% the first time and 99% after
* second extraction; tantalum to the extent of 80-82% the first time and 90-91% after
* second extraction. A part of the tantalum is apparently in a polymeric state and
is not extracted. These degrees of extraction of the two metals remain virtually un-
changed as the sulfuric &aid and hydrogen peroxide concontrations are varied within

ABSTRACTs The author mentions 3 practical problems of analytical
chemistry: methods for the analysis of complicated technical
and natural materials; methods for the determination of micro-
impurities; the elaboration of automatic inspection methods
for nToJuction, With reference to the anal,-tical method, the

TEXT: The authors studied the hitherto insufficiently investigated
formation conditions of oxalate complex compounds of zirconium in
acid medium. The physicochemioal analysis was aRplied for determining
the complex compound formation in the system Zr4+ - C 2042-. The
optical density of solutions was measured in ultraviolet light. The
authors found that the following three complex compounds form in the
above system depending on the concentration of the oxalic acid and on
the pH of the solution: ZrC204 2+9 Zr(C204)2, and ZrOC204. Their
formation was confirmed by the investigation of the*direction of motion
of the ions in electrolysis. The authors determined the dissociation

the absorption.of light in the ultraviolet range. It is 1.6-10-10. A
similar value was obtained from the equilibrium of the ferric thiocyanate
and oxalate complex compound. The dissociation constants were also
calculated for the complex compounds of Zr(C204)2 (- 4.6*10-8) (Table 3),
Zr(C204)3 2- (.. 1.9.10-4)~, and for Zr(C204)4 4- (= 5-08*10-1)- Furthermore,
the instability constant of the zirconyl-oxalate complex compound
ZrOC204 (. 2'.i-io-7) and the second instability constant of
ZrO(C204)2 4.57-10-4) were.calculated (Table 6). Finally, the
authors calculated the nomogram of the equilibria of the oxalate complex
compounds of zirconium and zirconyl in solution (Fig- 7)- It characterizes
the relatibn between the equilibrium conditions and the stability of
complex ions in the system. The following optical densities are shown in
tables 19 49 and 5: those of the isomolar series of the solutions Zr4+ in
0-5 and 1.0 M HC1 04 in Table 1, those of the system Fe3+ - SCN.- - Zr4+-

PERIODICAL: Ukrainskiy khimicheskiy zhurnal, 1960, Vol. 26, No. 4,
pp. 514-518
TEXT: In the introduction the authors state that zirconium exerts no
chromophoric effect. For color reactions with respect to Zr it is there-
fore necessary to use reagents that are colored themselves and do not
change their color in complex formation with Zr. The spectrophotometria
characteristic of the reagent and of the reaction product are of greatest
importance for the selection of the reagents. Five of these characteristics
are mentioned, and it is stated that it has hitherto not been established
which of them is of greatest importance in the selection of a reagent in
photometry. The following characteristics are mentioned: 1) The difference
batween the wavelengths of the absorption spectrum maxima of the complex
with Zr and the wavelengths of the reagent itself at the same pH; 2)
Card 1/3

relative, and 3) absolute difference between the molar coefficients of
light absorption of the complex and the reagent at X max; 4) relative and
5) absolute difference between the integral regions of the absorption
spectra of the complex and the reagent. This problem is discussed with
respect to the reagents for zirconium. A table shows the spectrophotometric
characteristics of 16 reagents. 1-6 are dyes of the triphenyl methane
type, 7-10 oxyketone dyes, 11-16 azo dyes,,-The curves of light absorption
were measured with the Cl~-M (SF-2M) spectrophotometer. A jo .. 3 mole
solution of zirconium chlorine oxido in 1 N hydrochloric acid was used.
The solutions of the organic reagents were used at jo-3 mole, except for
stilbazole, for which the concentration was 5-10-4 mole/l. The optimum
conditions of the reagent for zirconium, as well as the optimum pH were
determined. The spectrophotometric curves for xylene orange sere recorded
at pH 5, for thymol methyl blue in 1 N perchloric acid and for all other
reagents at pH 1.5. Data were found on the basis of the absorption spectra.
Fig. I shows the absorption spectra of the oomplexes and the reagents.
The detectable minimum is recommended as criterion for the sensitivity of
the reaction, The angle of inclination of the calibration curves (Fig. 2)

may serve as criterion for the photometric analysis. The calibration curves
were, as usual, recorded with the 4~3?K M-57 (FEK M-57) photocolorimeter.
In each case the respective reagent served as comparative solution. The
degree of the angle of inclination depends on the absorption spectrum and
corresponds to the molar ratio between the light absorption coefficient of
the complex and the reagent. Among all reagents investigated xylene orange,
thymol methyl blue, p-nitrobenzene azopyrocatechol, and phenyl fluorone
proved to be most sensitive in the photocolorimetric determination of
zirconium. There are 2 figures, 1 table,and 13 references: 5 Soviet.

TEXT: Methods used for determining Zr in ores containing I - 30 % ZrO2,

It has been found that for ores of this type the methods using salieylic, phenyl-
arsonic and phthalic acids are ineffective, because they do not ensure a suffi-
cient separation of Zr and Ti. Mandelic acid, phosphate-hydroxyquinoline methods
and the method using versene can be used for analyzing titanium-zirconium ores.
The latter method is least time consuming and produces satisfactory results. Its

um) were studied in the presence of excess pyrogallol. Tantalum
(niobium) pyrogallate also absorbs light. It was found that EDTA
acts not only as a Medium, but enters into the composition of pyro-
gallELte complexes of tantalum and niobium, forming compounds in the
ratio EDTA:Ta (Nb) = 1:1. The three-component systems form ternary
compounds which have 2 different addends in the coordination sphere.
The formation of new absorption bands (under the action of the EDTA)
is apparently due to a change in the state of the central atom in
a reaction of type NbO3 + H4YZ�NbOY*- +2H20. Graphs show the effect
of pyrogallol concentration on the niobium (tantalum) complexes and
other graphs show the effect of EDTA concentration on niobium (tan-

TEXT: The authors studied the composition and properties of salicylate
and pyridine salioylate complexes of titanium separated from aqueous solu-
tions in solid form. The solubility of titanium salicylate depends on the
pH of the solution. Fig. 1 shows the solubility of titanium salicylate as v
dependent on the pH of the solution. The formation of titanium salicylate
complexes from aqueous solutions proceeds stepwise. The investigation of
the composition of the crystalline titanium salicylate complexes shows
that the titanium saliovlate ratio in these compounds in dependence on the
pH of the solution in I : 1, 1 : 2, and 1 : 3. The pyridine salioylate
complexes of titanium were produced by adding pyridine to the aqueous
titanium salicylate solution, a fine crystalline yellow powder being fomed
