A study of the equilibrium extraction behavior of a series of representative attervalent lanthanide ions, Pr, Eu and Yb, was carried out with chloroform solutions containing N-benzoylphenylhydroxylamine, N-m-trifluoromethylbenzoylphenylhydroxylamine (HL) either alone or combined with 1,10-phenanthroline (phen). The results demonstrated that the lanthanides are extracted as LnL/sub 3/ x 2HL or in the presence of phen as LnL/sub 3/ x HL phen for Pr and Eu, and LnL/sub 3/ x 2 phen for Eu and Yb. The extraction constants, separation factors, and composition of adduct complexes for the two extractants were compared. 12 references, 4 figures, 4 tables.
