Abstract

Experimental data on solvent extraction of cerium (III) by solutions of oleinic acids in odimethylbenzene was obtained. After mathematical analysis of the dependences of the distribution coefficient from pH and composition of organic and aqueous phases was determined the structure and composition of solvate complexes and value of the Gibbs free energies and reaction equilibrium constant.
