“…However, the separation of americium by diamides of 2,2’‐bipyridine‐6,6’‐dicarboxylic acid follows the same trends as CMPO molecules. Introducing the aromatic ring into the amidic moiety shows sharp increases in metal distribution coefficients, and the subsequent substitution of the aromatic ring with alkyl groups also improves the extraction ,. The distribution coefficients demonstrate a tenfold rise when going from N ‐ethylanilide to N‐ethyl‐ p‐ alkylanilides of 2,2’‐bipyridine‐6,6’‐dicarboxylic acid .…”

“…Introducing the aromatic ring into the amidic moiety shows sharp increases in metal distribution coefficients, and the subsequent substitution of the aromatic ring with alkyl groups also improves the extraction ,. The distribution coefficients demonstrate a tenfold rise when going from N ‐ethylanilide to N‐ethyl‐ p‐ alkylanilides of 2,2’‐bipyridine‐6,6’‐dicarboxylic acid . The effect on metal affinity of a substituent in the pyridine ring was studied for 6,6’‐bis(1,2,4‐triazin‐3‐yl)‐2,2’‐bipyridine‐type (BTBP) and 2,9‐bis(1,2,4‐triazin‐3‐yl)‐phenanthroline‐type (BTPhen) compounds, but not for heterocyclic diamides.…”

“…Various classes of soft donor ligands have their own limitations and advantages . Mixed soft‐hard donor ligands have been explored and found to be promising for this An/Ln separation . Hexaalkylnitrilotriacetamides (HRNTA, Figure ) represent a class of mixed ‘N’,’O’ donor ligands, where the ‘N’ atoms present at the centre of the ligand structure can also participate along with the carbonyl ‘O’ atoms of the amide groups.…”
