Abstract

Various organophosphorus ligands with a combination of different donor sites were synthesized and evaluated by solvent extraction studies for the complexation of Am (III)/Eu (III). Among the ligands with a glycolamide backbone, those with mixed amide and PO donor sites and a central oxygen or nitrogen atom showed a reasonable extraction of Am (III) and Eu (III). Ligands with a central oxygen atom exhibited selectivity towards Eu (III), and those ...
