        <p>Получены данные по экстракции церия (III) и иттрия (III) растворами олеиновой и нафтеновой кислот в о-ксилоле из нитратных сред. По зависимостям коэффициента распределения от рН и состава органической и водной фаз вычислены константы и энергии Гиббса экстракционного равновесия, определен состав сольватных комплексов.</p>

        <p>Experimental data on the solvate extraction of cerium(III) and yttrium(III) by solutions of oleic and naphthenic acids in o-dimethylbenzene have been obtained. After mathematical analysis of the dependences of the distribution coefficient on pH and the composition of the organic and aqueous phases, the structure and composition of the solvate complexes, as well as the values of Gibbs free energies and equilibrium constants of the reaction were determined.</p>
