Solvent Extraction Studies for the Separation of Trivalent Actinides from Lanthanides with a Triazole-functionalized 1,10-phenanthroline Extractant

2-Methylpyrrolidine derived 1,10-phenanthroline-2,9-diamides: promising extractants for Am(iii)/Ln(iii) separation

“…Bis-triazinyl heterocyclic compounds (SF(Am/Ln) > 100) have the highest selectivity towards americium(III) among polyidentate ligands, but the extraction rate of these compounds is low. 15 Diamides of N-heterocycles are a promising class of compounds characterized by moderate selectivity to Am(III) in the presence of lanthanides. These ligands are very attractive due to their high extraction rate and a wide possibility of structural modifications to reach selectivity to americium.…”

Selective extraction of trivalent actinides using CyMe4BTPhen in the ionic liquid Aliquat-336 nitrate

“…In former studies, the room-temperature ionic liquid Aliquat-336 ([A336][NO 3 ]), was identied as a promising candidate that could be used as an alternative for aliphatic diluents in trivalent MA partitioning processes. [38][39][40][41][42][43] This compound has a higher ash point (T Fp $ 110 C) than other diluents oen used in the nuclear fuel cycle: kerosene (T Fp $ 37-65 C), ndodecane (T Fp $ 71 C) or 1-octanol (T Fp $ 81 C). 34,44 The polar nature of the ionic liquid diluent tri-n-octylmethylammonium nitrate, [N 1888 ][NO 3 ] (Fig.…”

Chelating Extractants for Metals

“…The extraction behaviors of phenanthroline (102), bipyridine (103), and pyridine (104) derivatives towards Am (III) and Eu (III) dissolved in highly concentrated nitric acid solutions were compared [99]. 3-Nitrobenzotrifluoride was used as the diluent.…”
