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 PmA3 is extracted into the organic phase with the extraction constant log Kex = -4.35. The stability constant βn of the complex PmA3 has been calculated by the Leden method.
