ABSTRACT: This is an historical survey on the evolution of colorimetry
and nephelometry, beginning at the origins (Pliniua Secundus
23-79, Ar-Razi 665-925) and gathering the statements of va-
rious chemists of the past centuries, which are in one way or
another connected with the methods under consideration (Refs
1-16). From among the Russian scientists G. ftaber, G. Remus,
and L. Blyumentrost are mentioned, who at the beginning of the
18th century had specialized in the analysia of mineral watereq
and also M. V. Lomonosov, who lived from 1711-1765- Even to-
Card 1/2 wards the end of the 18th century many reactions were employed

in gravimetry which lead themselves advantageously also to the
colorimetrie and the nephelometric methods. Summarizing the
work done until the beginning of the 19th century in the field
of colorimetry, it is stated that colorimetric investigations
were then used for the solution of qualitative problems only.
Also the physical work done in the field of light and of the
coloring substances is briefly outlined from the historical
viewpoint. In this connection the discovery of the absorption
law was ascribed to P. Buger in the year 1729, 31 years before
Lambert. Concerning physical work the following statements are
made: All the theoretical work done in the field of optics
and photometry, up to the beginning of the 19th century, can-
not be considered as a foundation of the methods of oolorime-
tric analysis. The theoretical foundation was not laid before
Card 2/2 the 19th century. There are 20 references, 11 of which are
Soviet.

ABSTRACT: Various scientific treatises have permitted the statement (Refis
2,6,i1-13) that the absorption spectra of the rare earth ele-
ments change in the course of the formation of the complexes.
The absorption maxima are displaced in dependence of the con-
centration of the complex forming addition and of the change
of the pH-value of the solution. This displacement permits con-
clusions to be drawn on the stability of the various complex
compounds of the rare earth elements as Niell as on the pH range
in which they exist. From this point of view the investigdtions
mentioned in the title were carried out. The SF-4 apactro-pho-
tometer was employed for the measurement of the absorption
Card 1/3 spectra whilst the pH-value -,f the solutions was ascertained

In order to determine the exact position of thb maxima .,f' r-e
samarium ion the initial solution was taken spectro-pho~~'!'~e-
trically (The respective data are found in table I and in Aig
1) and the data obtained were then compared with those of
Prandtl, Ref 10. The molar absorption coefficients of the prin-
cipal maxima agreed with data from publications (Refs 3"'S'9).
The further modifications of the samarium spectrum in the p-.e-
sence of the complex forming addition were observed ot tLe ware
length of the absorption maximum 4=401mg. The spectra of solz-
tions having different pH values and different ratios of saxa-
rium and complex-forming additions were taken (Pigs 3 and 4)-
The limits of the pH values within which the various complex
compounds are capable of existing, are compiled in the tables
3,4,5. In the pE-value field 1-12 2 complex compounds of sama-
rium with the citric acid and also trioxyglutaric acid were as-
certained, as well as one cumpound with the laotic acid in an
Card 2/3 acid medium. In basic media only hydroxide precipitates are

formed. The stability of these complex compounds was investi-
gated with respect to hydroxyl ions, oxalate ions and fluoride
ions. Photometrical data permitted the conclusion to be drawn
that the compounds with citric acid and trioxyglutaric acid
exhibit about the same degree of resistance, and that they are
by far more resistant than the compound with the lactic acid.

ABSTRACTi All experiments on the distribution of thorium between an or-
ganic phase (chloroform) and an aqueous phase took place at an
initial co centration of thorium in the aqueous phase equal
to 1.0.10-9 g-ion/1 and an ionic strength of 0.1. The temper-
ature was 25 + 0.10. For the determination of the composition
of the complexes which form in the aqueous phase between selen-
enoyl-2-acetone and thorium, the distribution curves of thorium
selenenoyl-2-acetonate were plotted at three different reagent
concentrations in the chloroform layer. The measuring results
are shown in table 1. In figures I and 2 the distribution of
Th4+ in the system CHCl 3 - H 20 is graphically shown in dependence
on the pH-value and in dependence of the log sigh I at various

retical expectations for complexes of the type
9 An(N-n)+ (M - metal, A - addendum, N - charge of the metal

course of the curves obta i ed Indicates that the complex does
not contain molecules of the org*anic solvent. Under the above
conditions, only complexes of the form
Th An(4-n)+ are therefore formed. The authors also investigated
the dependence of the distribution coefficient q on the con-
centration of selenenoyl-2-a.cetone in the aqueous phase. The
Card 2/4 results are shown in table !,. Table 4 shows a compilation of

processes in the system selenonoyl-2-aaetone - Th(iv) - GHCl

results obtained were used for a determination of the peroen-
tage distribution of thorium between complexes of various
composition as a function of pA ( pA - negative logarithm
of the concentration of free reagent). The corresponding
curves are shown in figure 6. Thorium-selenenoyl-2-acetonates
differ considerably, on the basis of their physico-chemical
characteristics, from the complex compounds of thorium with
other reagents which contain the same reactive grouping. The
former possess considerably higher stability constants and
distrihution coefficients than, for example, the corresponding
acetylaoetone complexes of thorium. Selenenoyl-2-acetone is,
therefore far better suited as a reagent for the extraction
of thorium from aqueous solutions than acetylacetone, which
is frequently used for this process. There are 6 figures, 4
tables, and 15 references, 5 of which are Soviet.

theoretical principles goveraing the method dealt with here,
the various forms of the titration curves (Fig 1), subdivided

of the method it is mentioned that a large part of the papers
contained in publications regarding the subject deal with
spectrophotometric redox titrations, and reactions under
formation of complex compounds are applied to a specially
great extent, the complex former being mostly ethylene diamine
tetraacetic acid or its sod'Aum salt. A few papers (mainly from
foreign publications) are referred to, and the respective
absorption spectra (Figs 2, 3, 5) are depicted. Finally, a

TITLE: Investigation of Com2lex Formatiod-in Solutions by the
Distribution Method
PERIODICAL: Uspekhi khimii, 1960, Vol 29, Nr 2, pp 234-268 (USSR)
ABSTRACT: The possibility of using the distribution method for the
investigation of complex compounds in solutions is considered
in this paper. The foundations for the distribution method
(or extraction) were laid down by Nernst in 1891. But it was
not until 1941 that the first experiments were made to find
a quantitative relation between the distribution ratio of the
metal in the system and the parameters of the latter. As may
be seen from existing publications, informations on the composi-
tion and physicochemical characteristics of complex compounds
in every system can be obtained by the treatment of experimental
data with corresponding mathematical methods. Theoretical
principles of the distribution method and the corresponding
equations are quoted in this paper. On investigating systems

process, proceeds in stages, and no stage must be omitted. The
investiKation consists of the following stagess 1) Determination
of the dissociation const-nts of the organic reagent ILA with
selected constant Ionic strength and solution temperaturel
2) Investigation of the distribution of the reagent between
the aqueous phase and at least two organic solvents in a
sufficiently wide range of HA concentrations in the solvent
layer 3) Determination of the concentration range of metallic V/
ions in the aqueous phase in which the formation of multi-
nuclear complexes and hydrolysis products may be neglected;
4) Solution of the problem as to whether complbxes can be
formed which contain molecules of the used organic solvents;
5) Determination of the composit.%on of complexes which are
formed in the aqueous phase; 6) Drawing of the distribution
curve with rational selection of the factors determined
and their mathematical treatment by one or more computation
methods (Refs 48-52, 260) etc. In some cases, one experimental
result can be treated by mathematical as well as graphical
methods. Nith regard to the latt,ar, it is referred to references

with organic and inorganic addenda, use of polar and non-
polar solvents, etc), sometimes a corresponding modification
of the respective equations may be necessary, the peculiari-
ties of the system to be investigated being taken into
consideration. Mathematical methods, which are used in the
investigation of complex formation by the method of metal
distribution between two immiscible solvents, may be con-
sidered well developed at present. All complex types, which
can be formed in aqueous solutions, were theoretically
investigated. Many of these complexes were investigated
experimentally, at least in solutions with low and constant
ionic strength. It may be concluded from the theoretical
principles and the conaideration of the great number of
systems investigated by the dii3tribution method that this
method is one of the most reliable, fastest, and relatively
simplest methods for the investigation of complex formation
in solutions. A. K. Babko, A. ~% Pilipanko, I. P. Alimarin,

TEXTz A method was developed for determining about 10 M solutions of
rare earths and of thorium with Komplexon III in the presence of arsenazoi
I as indicator. Thorium and the rare earths were successively determinW
in a sample. Compared with visual titratio-a, sensitivity was improved by
3 to 4 orders. For the rare-earth determination, the following was added!
to solutions containing the rare earths in quantities between 10 Ag and
1.0 mg: 10 ml solution of areenazo I (I-10-5M), 1.0 ml of 0.1 N hydro-
chldric acid, 3 ml of 25 % urotropine solution (to obtain pH 6.6) and
5 ml of 1 % ascorbio acid (to reduce Ce4+). The product was then topped
up to 100 ml and mixed'. 20 ml of the mixture was titrated in a cuvette.
After adding 0.1 ml of Komplexon III solution at a time the optical den-
sity wqs measured at 575 m~L. The end point was determined graphically.

Checks revealed an error of less then 1 %. Thorium was determined at pH
2. It is important that the indicator concentration be at least as high
as that of thorium. The following was added to a solution with 20 4g to
0-5 mg of thorium; a 20-ml solution of arsenazo I (1-10-4M) and 10 ml of
0.1 N hydrochloric acid. The further courl3e i,3 as above. Checks revealed
an error of 0.3 %. The successive determination of thorium and the rare
earths is possible for a Th:RE ratio between 1:1.and 1000, but is not if:
Th:RE = 100:1. For determination purposes, 10 ml of 0.1 N hydrochloric
acid and 20-m1 solution of arsenazo I (10-5M) -Nere added to 0.02 - 0.05mg
of Th and 0.1 - 1.0 mg of RE, and topped up to 100 ml. 20 ml was titrated~
as above; 1 ml of 25 % urotropine solution was then added in the cuvotte,i
and the rare earths were titrated. Checks roviaalod the same error limits~
as above. For comparison a monazite sample was analyzed by spectro-
photometric titration and by the oxalate method. Yu.-A. Chernikhov and
F. V. Zaykovskiy are mentioned. There are 2 figures, 4 tables, and

ABSTRACT: Absorption spectra of complex compounds
prase6dymium with 7-iodo-8-hydroxyquinoline-5 11WRc acid were studied. A strong
hypsochromic shift of the absorption band of this reagent in alkaline media, combined
with the bathochromic shift of the characteristic absorption maximum of the complex
formed by this reagent with neodymium, creates favorable conditions for determining
neodymium at Xmax 581 mv. Neodymium was determined in Nd-Pr and Nd-Sm pairs in water-
-alcohol solutions at pH 8.0-11.0, using two wavelengths: A, 581 mij and A2 590 mli.
The data show that the method used permits a suf`:ciently accurate determination of
neodymium in praseodymium and samarium in amounts of 0.0043-0.043 mg/ml (or 3-10-5
