Abstract

Dithiophosphinate ligands with groups linked together by a bridging spacer to take advantage of a chelate effect for improved selectivity have been characterized. Extractions with each ligand were performed with the ligands dissolved in methylene chloride and the metal salts dissolved in aqueous phase at pH 4. H₂L1 was found to have good differentiation between UO22+ and Gd³⁺, but only resulted in 50% extraction. H₂L2 had lower selectivity; however, copper extractions approached 95% after 24 h.
