Abstract
Data on the extraction of cerium(III) and yttrium(III) by naphthenic acid solution in o-xylene from chloride media were obtained. The experiment showed W-shaped dependence of the distribution coefficient of cerium(III) and yttrium(III) on the Cl content in the equilibrium aqueous phase. The minima of the dependence are explained by the formation of non-extractable complexes MeCl2+ and MeOH2+, the maxima - by the increase in the degree of dissociation of naphthenic acid and the increase in the ionic strength of the solution.
