Abstract

The extraction of cerium nitrate from aqueous solutions by a solution of oleic acid in o-xylene was studied. The dependence of the distribution coefficient of cerium nitrate on the water-hydrogen index and on the volume of the organic phase was revealed, while the ratio between the concentrations of oleic acid and cerium remained constant. The solvation number at ex-traction of cerium nitrate by oleic acid was determined. The mechanism of the reaction was established. The equilibrium constant and Gibbs energy of extraction were calculated.
