A-133211,ACT: The Institut Vhimllcheakoy fiziki M: SSSR (Institute for
Chemical Physicn, AS USSR) collected experimental material
concerning the distance of ejection of various portions of
earth ejected by an explosion. The material is in many respects
of some interest. When carrying out such experiments, it in
necessary first to divide the area of ground before the
explosion takes place within range of the crater to be formed
into sections, and after the explosion the manner in which the
fragments of earth are distributed over the said area must be
determined. Various parts of the area -acre marked by means of
radioactive indicators. Before the explosion 50-60 ampoulea

TEXTs Derivatives of 2,3,7-trihydroxy-6-fluorone which are substituted at
C9, give color reactions with titanium in weakly acid solution (Ref.1),
Most of these derivatives however hydrolyze at high pH, and precipitate.
By introducing sulfo groups into the molecule of trihydroxy-fluorone the
tendency toward hydrolysis may be eliminated and the sensitivity of the
color reactions is increased. Such a highly sensitivp reagent for the
photometric determination of titanium is q-(2',4'-diaulfo-phenyl)-2,3,7-
trihydroxy-6-fiuorone (I), the syn+.hesis of which has already been
described earlier (Ref.4).

sensitivity for the titanium determination (Table 1) The authors of the
presont paper determined the optimum conditions for the titanium determina-
tion with an alcoholic solution of disulfophenyl trihydroxy fluorone. The
optimum pH value for the determination at 6 and is beat brought about
by means of a pyridine-hydrochloric acI4 b~iffpr solution. At this pH the

molar extinction coefficient of the violet complex solution has the
value 108000 The optical densities of solutions of the complex were
measured in alfMC-5f (FMS-56) photometer with a color filter permeable
to light of Tne wave length 570 m/k. The absorption curves of solutions of
the pure reagent and of the titanium complex at pH 6 were taken in a
CI-4 (SF-4) 8pectrophotometer The absorption maximum of the complex lies
at 570 m,&, where the pure reagent absorbs to a very small extent (Fig 2).
The composition of the complex was investigated by two waysi by the method
of isomolar series and by the method of molar proportions Titanium was
found to react with disulfophenyl trihydroxy fluorone in a molar ratio of
Ti : R - I j 2. The solutions of the complex obey Beer's law (Fig.6) The
least titanium quantity determinable is 0.01PIgIml. The maximum colora-
tion of the solution is attained 10 minutes after the reagent is addea,
and remains stable for 12 hours. The disturbing influence of germanium,
tin(IV), antimonv(III),and molybdenum may be eliminated by masking with
thioglycolic acid; zirconium, aluminum,and iron may be masked with com-
plexon III. The optimum quantities of these masking substances are
0-3 ml 10% thioglycolic acid, 0,1-0.5 ml of a 10% complexon solution for

5 ml solution The authors used the described method to determine traces
of titanium in pure germanium and silicon. After dissolution of the
sample most of the germanium is distilled off in the form of tetra-
chloride, whereas in the case of silicon most of it is distilled off as
silicon tetrafluoride. Titanium is determined in the residue by the method
described. In this way up to 5-10-6% titanium may be determined in
silicon or germanium. The course of the determination is described in
detail, and Table 3 shows some of tile results obtained. The present
paper has been presented at the section of analytical chemistry of the

TITLE: Derivativen of Trioxy Fluorone an Reagi-4nts on Tellurium
PERIODICAL: Ukrainskiy khimicheskiy zhurnal, 1960, Vol. 26, No. 3,
pp. 368-372
TEXT: The authors wanted to find out the behavior of tetravalent tellurium
toward co-,rpoundB containing the orthooxy quinone grouping ani being reagents
for ions of the tetravalent metals germanium, lead, titanium, zirconium,
hafnium, and thorium. The authors were particularly interested in the de-
rivatives of trioxy fluorone and examined a total of 15 derivatives of
2,3,7-trihydroxy-6-fluorone. Experiments revealed that at pH 4-6 the tetra-
valent tellurium reacts with the majority cf the trioxy fluorones examined.
The trioxy fluorones specified in Table 1 were the most sensitive in re-
acting. The subatituents on C 9 were 1) propyl, 2) P-hydroxy-a-naphthyl,
3) 4-hydroxy-3-methoxy phenyl, 4) 2-methoxy-3,4-methylene dihjdroxy-()-ethY1-
P-methyl amino phenyl, 5) trichloro methyl, 6) 4--nitrophenyl, 7) 5-nitro-
2-h,ydroxy phenyl, 8) 3-nitzo-2-hydroxy phenyl. Reagento 1, 2, 5, and 6

have a sensitivity of 0.2 y/ml,
an I the reagents arid 7, i~ aLri:i _t ivi t.y
of 0.4 Y/ml. The introduction of ethyl alcohol into the solution prevento
the reagents from co-precipitating, but it also prevents their reactang
with tellurium. No more than 10 alcohol rnuot be contained in the solution.
With 20% alcohol, tellurium does not react at all. A study of the spocifici-
ty showed that under these conditions trioxy fluoronoo react with Al, Fc,,
Sc, Au (III) , In, Ge, Sn (IV) , Sb (III) , Ti , Zr, W, T'o, U, Ta, !Tb, V (V)
Te (VI), As(V), nnd Sb (V) do not react. Se reacts neither in tetra- nor
in hexavalent form. Summing up: The Aerivritives of 2.3.7-troxy fluorone
substituted on C in weakly acid medium (pli 4-6) %ith tetravulent telluria,,L
give rise to coAred complexes, whose composition corresponds to the ratio
Te:R - 1:2. It was proved that 9-propyl-2,),7-trihydroxy-6-fluorore (propyl
fluorone) and 9-p-hydroxy-a-naphthyl-2,',7.-trihydroxy-6-fluorone (P-hydroxy
a-naphthyl fluorone) are suited for the photometric determination of te'L.
lurium. The solutions of complexes at optimum p1l 4-5.6 obey Beer's lfw
at a tellurium concentration of 0.4 - 2.4 Y/m ''. Table 2 shows the determina-
tion of tellurium in the presence of other elements. There are 4 figure~l

TITLE: Determination of Iodine Hioroimpurities in Elementary
Silicon
PERIODICAL: Zavodakaya laboratoriya, 1961, Vol. 27, No. 1, PP- 15-16
TEXT: A method was developed to determine iodine microimpurities in
silicon. The impurities are extracted with benzene after oxidation of the
iodide to elementary iodine. The course of analysis is indicated: 1 or
0.5 9 of finely ground silicon is dissolved in a 20-m1 3 N sodium
hydroxide solution which is heated simultaneously. 5 ml of sulfuric acid
1:1 is added to the solution, and water is added until an amount of 150 ml
is reached. The sample is placed in a sepa-rating funnel, mixed with sodium
nitrite, and twice extracted with benzene. The iodine content is determined
colorimetrically. Results are given in a table. By this method it 1 8
possible to determine 0-5 r of iodine in 1 g of silicon, i.e., 5 . 10-5%.
This method is mainly intended for semiconductor silicon which contains
small iodine impurities after production by the iodide method. There is 1

TEXT. The complex formation between Geo 2' 4rO C12 or SbCl3and phenyl
fluorone and between Sc 2(SO4)3and propyl fluorone was studied spectro--
scopically in acid media after stabilivation with gelatins to ascertain
whether the metal ion substitutes two H atoms 'in the diphenol or one H atom
in the o-hydroxyquinane. A now scheme, based -on the solubility productq
is given fGr the evaluation of the speotrophotometric data; this was
iieceseary because of the low solubility of the complexes. The complex
formation with Zr was studied in 0.2 - 0.8 N HCl and showed that only a
1:2 complex forms (optimum 0.2 - 0.3 N HCI). This was confirmed by both
the isomolar series and the molar ratios. The Zr complex is thus
consistent with other Me IV trihydroxy fluorone complexes. A study of the
change in optical density as a function of the pH showed that only one R

on AV-17 anion exchang-ir (made from styrene, divinylbencene, and
trimethylamLne (see: Z' 'I. f. kh., v. 36. no. 11, Nov 1962, 2465-
2468)) treated with "toron" (1-(o-arsonophettylazo)-2-naphthol-
3,6-disulfonic acid) to form a "reverse anion exchanger" which acts
as a cation exchanger toward Th only. A "reverse anion exchanger"
is defined *s one treated with an organic compound containing both
a group reacting selectively with the Lon to be separated, and an
acid group (preferably a sulfo group) for attachment to the origin-
nPlanion exchanger. Separation of Th was carried out in a glass
column 20-25 cn long and 0.8 cm in diameter. Three grams of AV-17
anion exchanger (pretreated with water and an alkali) was placed
in the glass column, treated with a 0.5% toron solution, and washed
with water. The Th-containing influent (20-30 ral), acidIfied with
0.2 g ascorbic acid (to an acidity equivalent to 0.05 N HC1), was
passed through the column at a rate of 0.5 nl/min. The adsorbed
Th was than eluted with 1 N IICl. The amount of Th so separited was
determined by the spectrophotometric method (V. 1. Kuznctsov, ZhO'Kh,
13, 914 (1944); S. B. Savvin, DAII SSSR, 127, 6, 1231 (1959)). After
elution the anion exchanger nay be used again without additional
treatment with toron. Microquantities of Th (down to 1 X 10-4%)

also studied, using Y91, Eu 2, Eu'54, Pm'47, Fess, and Fe". Tabulated
data on the radioactivity of the tolutions before and after they

TITLE: Arsenazo I as reagent for the photometric determination of scandium
PERIODICAL: Ukrainskiy khimicheskiy zhurnal, v. 29, no. 2, 1963, 198 - -'o);
TEYT: The reagent arsenazo I was first described by V. 1. Kuznetsov (DAN,
v. 31, 1941, 895) for the determination of uranium and rare earths. The present
authors investigated this reagent for photometric determination of scandium in
some natural and technical materials. The optimum PH was found to be 7.9 and was
maintained by a borate buffer In further studies. The maximum light absorption of
the arsenazo solution at PH 7.9 lies at 500 r;i~L and of the coirplex with sc,-Uldiur,
at 542 m~x . Thus the optimum optical density for scandium determination is at
570 m p- . The maximum colour intensity was observed at 3 - 3.5 fold excess of the
reagent In relation to the c~candiurn content in Zhe .9olution (in ti-itilell) , Thr., col-
our develops in 5 min remaining unchanged for Geveral hours. Tne miolar abnorption
coefficient of the s&andium complex was determined by the saturation method at
570 mi,.Awith 1.73-10 . Under optimum conditions the solutions of the scandium

complex follow Beer's law in a wide range of concentration. Dete i tion of t
effect of the concentration of hydrogen ions cnthpformation of the complex showed
a mean value logK = 5.41. Scandium forms with arsenazo a 1:1 comnplex. The authors
assume that arsenRzo reacts with scandium in the quinonehydrazonic form. The scan-
dyl ion substitutes the hydrogen of the arsone group, while the hydrazo group has
a coordination bond with the quinone oxygen and nitrogen. A met'hod for the deter-
mination of scandium at a content up from 0.001,%, in various materials (coal ash,
granite, amphibolite, cassiterite slags, wolframite) was developed. The interfer-
ing elements are removed by the procedure described by the -authors for scandium
determination with propy1fluorone (Zav.lab., v. 28, 1962, 401). The aqueous ex-
tract after the s6paration of scandium by rhodanide-ether extraction, in evaporat-
ed, the dry residue calcinated at maximm 7000C, digested with 2 mi arjua regia
and evaporated, then digested with 2 ml 8 N IM and filled up to 50 ml with 23 ml
0.1 N HC1, 0.5 ml %, -solution of ascorbic acid, I ml 0.25% ortho-phc~nanthroline,
and 0.05 M borax solution. After mixing for 20 min the density iF measured at
570 m~_L also of a solution prepared in the same way, but without scandium. The
scandium content is determined from a calibration curve. There are 4 figures and
2 tables.

ABSTRACT: Complexometric determination of tetravalent germanium in
GeO was accomplished by use of a heated solution of the disodium
sal? of ethylenediaminetetracetic acid and a 2.5 fold excess of
complexone III. Changing of the anion into the cation form was found
to proceed slowly, and complex formation occurred quantitatively at a
0.02-0-05 N H01 acidity. As one mole of aeO binds 1 mole of complex-
one, the Ge gram - equivalent is 72.6, The gx~ess of complexone was
titrated off with zinc sulfate and a color indicator. Standard devia-
tion errors were + 1.2% for 15-200 mg Ge and + 4.6% for 0.2-3 mg Ge

ITOPIC TAGS: photometric analysis, niobium, titanium, titanium compound
ABSTRACT: The proposed method for dotermination of niobium In metallic
titanium and titanium tetrachloride is based on separation by extraction
with a solution of tribenzylamine In CHC1 from 11 M HC1 and final
determination photometrically using orthohtrophenylfluorono. The
method makes it possible to determine down to 0.02 microgrnms of n1obium
in 1 ml. The determination of nibbium is not interfered with by the
following other impurities (in microgravis/ml); Ta--0,4; T1--4; Zr--8;
Sn--2; Mo--2; W--l; Ga.--4; Sb ;;p40; Fe ;>300, Witb the use of extraction
with an 8% solution of ~ribenzylomine In chloroforms a check using the
radioactive Isotope NbT'~ showed that in a single extraction from 11 M

hydrochloric acid, at a. ratio of 100:25 between the aqueous and organic
phases, 87% of the niobium went over into the organic phase. 0.1 M
hydrochloric acid was a better extracting reagent, In a single
extraction, with a phase ratio of 50:50, 94% of the n1oblum was
extracted. Titanium was not extracted and Its presence in the solution
in the amount of more than 0,5 grams did not interfere with the
extraction of niobium. Orig. art. has: 1 table.

ABSTRACT: The photometric determination uf impurities in tantalum is described. It has!
a sensitivity of 10-41 and requires all the precautionary measures used during '.he
analysisof high-purity metals, including the running of blank experiments under con-
di~ions of sample analysis. The photometric determination is preceded by extraction of
the analyzed element (Fb, Cu. Fe, Nip or Sn) from the tantalum sample, by extraction
durIng the determination of tantalum in Zr, Bi. and Zn in the form of a fluortantalate
co4lex, and by dotermination of chromiun after separation of the tantalum by hydolyd3.
Lead and cadmium are determined by dithizone after extraction of the lead and cadmium
(iWthe form of dietbyldithiocarbaminate3) from acid modiun with cbloroform. The inter-
fering effect of other elements is eliminated by washing the extract with alkaline

moirically with paranitrophony1fluorono after oxtrartion of tho tin from the sulfate
medium with chloroform in the form of diithy1dithiocarbaminate. This Is mndo sL-Ularly
to the determination of tin in niobitan (11. B. L,',bedeva, V. A. Nazarenko, Trudy ror-Assii
po anaticheskoy khimlip Izd, Ali SSSR, XI, 287, 1960). It in convenient to determine
some impurities after separating the tantalum from them. This can be done by the ex-
traction of the fluorotantalum complex with ketones (e.g., cyclohexanono) from its
solution in HF and H 0 or H S040 while Zr, Ti, BI, and Zn car, be determined in the
aqueous phase: Zr vrit p'heny1fquoronev Bi b7 the Iodide-ketone method, and Zn with
