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 P=O 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 with a central nitrogen atom towards Am(iii). Ligands with P=S donor sites and a glycolamide backbone did not show any reasonable extraction. Amongst the ligands with a malonamide backbone, high extraction efficiency was observed for the ligand with electron-rich substituents on phosphorus, however, with almost no discrimination between Am(iii) and Eu(iii). The extraction efficiency of different ligands towards Eu(iii) was confirmed by microcalorimetry.
