The novel and fully combustible hydrophilic 1,10-phenanthroline-2,9-dicarboxamide (1) was synthesized and investigated as Am(III) stripping agent in a simulated advanced hydrometallurgical process, in comparison with two other 1,10-phenanthroline-based ligands 2 and 3. The stripping efficiency and the Am(III)/lanthanides(III) selectivity of the TODGA (org)/phen-derivative (aq) extracting system were studied under several experimental conditions by liquid–liquid extraction tests. The results obtained clarify the main limitations of these ligands in the scope of the hydrometallurgical reprocessing but also enable to get indications to steer future investigations in the domain of the selective An(III) recovery for the advanced reprocessing of Spent Nuclear Fuel by hydrophilic ligands.

Abstract
The novel and fully combustible hydrophilic 1,10-phenanthroline-2,9-dicarboxamide (1) was synthesized and investigated as Am(III) stripping agent in a simulated advanced hydrometallurgical process, in comparison with two other 1,10-phenanthroline-based ligands 2 and 3. The stripping efficiency and the Am(III)/lanthanides(III) selectivity of the TODGA (org)/phen-derivative (aq) extracting system were studied under several experimental conditions by liquid–liquid extraction tests. The results obtained clarify the main limitations of these ligands in the scope of the hydrometallurgical reprocessing but also enable to get indications to steer future investigations in the domain of the selective An(III) recovery for the advanced reprocessing of Spent Nuclear Fuel by hydrophilic ligands.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
