ABSTRACT: The solubility of lanthanam dibutylphosphate in 112S04 and F1NO,-j
was determined to obtain data required for the processes of dialkylphosphoric
acid extraction of the rare earth elements. As the nitric and sulfuric acid
concentrations increased, the solubility of the lanthanum dibutylphosphate therein.

ion point in the curve at concentrations slightly above 0. 2N. At low hydrogen 'on

ABSPRACTr The extraction of rare earth elements (R. E. E.) and thorium from sul-
furic acid solutions with A Oel48 M solution of di-iso-butylphoophoric acid in
kerosene has been studied. The R. E. E. and thorium vas extracted from aqueous
solutions containing the same amounts of the studied materials but with varying
sulfuric acid concentration from 0.01 to 8.5 mole/liter., The volume of di-iso-
butylphosphoric acid was also kept conetant. Results of extraction show that
R. E. E. and thorium: are fully extracted vith di-iso-butylphosphoric acid in
kerosene only at a certain concentration of H2S104. With an increase of H2SO4
concentration, the percent of extracted elements sharply decreases* Yttrium

ABSTRACT: The formation and stability of dibutylphos xes of thoriumland
phate comple
rare earth elements was investigated. The structure and stability of -fh-esecomplex-
es were derived from stlidying the kinetics of oxidation of potassium iodide catalyz-
ed by thorium and rare earth elements. In all experiments the total volume was 25
ml. In the experiments with thorium, 5 ml of 0.2 molar acetate buffer were added
to an aqueous solution of thorium chloride. This was succeeded by a solution of
dibutylphosphoric, acid, potassium iodide, and starch. After the introduction of

hydrogen peroxide, the mixture was held at 25 1 0.010C and the optical den:Aty of
the solution was measured using a FEK-M photoelectrocolorimeter. The final concen-
tration of potassium iodide was 4-10 4 molar and of hydrogen peroxide was 3.4-10-4
molar. It was found that n-dibutylorthophosphoric acid VA) reacts with thorium
chloride to form a complex of a general formula: ThOHA2 . This complex is inactive
as a catalyst for oxidation ol potassium iodide by hydrogen peroxide. The logarithm
of the stability constant of this complex at a zero ionic strength is equal to 5.06t
*0.06. The dependence of the logarithm of stability constants UgB) of qomplexes
of rare earth elements with dibutylphosphoric acid (general formula LnA2'r) upon the
specicif atomic number of elements is shown in fig. 1.
