Abstract

A study of the dependence of distribution of Pm(III) between aqueous phase ( perchlorate medium) and Freon 113 (or a Freon 113-benzene mixture 2 : 1) on pH and pA has shown that the complex PmA<sub>3</sub> is extracted into the organic phase with the extraction constant log <i>K</i><sub>ex</sub> = -4.35. The stability constant β<sub>n</sub> of the complex PmA<sub>3</sub> has been calculated by the Leden method.
