The solvent extraction of lanthanides (Ln) with N-m-nitrobenzoyl- and N-m-cyanobenzoyl-N-phenylhydroxylamine, was investigated. The representative lanthanides (Yb, Ho, Eu, Pr and La) were all found to extract with compounds as self-adducts of the form, LnL{sub 3}(HL){sub 3}, where L and HL denote the ligand anion and neutral ligand, respectively. The extraction constant and separation factor were compared with those of the N-p-octyloxy derivative bof N-benzoyl-N-phenylhydroxylamine previously reported. The correlation between extractability, mutual separability of lanthanides and acidity of the reagent were discussed. 14 refs., 4 figs., 3 tabs.
