Abstract
A current scan polarographic and chronopotentiometric examination of transfer processes involving tervalent lanthanides, Ln, and methylene bis (diphenylphosphine oxide), P, in a dichloroethane/aqueous phase pair has resulted in the finding that the ligand diffuses into the aqueous phase and reacts with an Ln(SO4)+ ion to give a singly charged complex Ln(SO4)Pn+, where n is 1 or 2, which then transfers under the influence of the electrical field into the organic phase.Keywords
