Times Cited Count：19 Percentile：61.1(Chemistry, Analytical)Alkyl diamide amine (ADAAM), a new high-performance reagent with a simple structure, was examined for the mutual separation of Am(III) and Cu(III). The combination of ADAAM and Tetraethyldiglycolamide (TEDGA) as a masking agent shows selectivity for Am(III) over Cm(III) in highly acidic media with separation factors up to 41.

Hexaalkyl-nitrilotriacetamide (NTAamide) was evaluated for the separation of MA(III) and RE(III). NTAamide is a multidentate ligand comprising one soft N-donor atom and three hard O-donor atoms as part of its central frame. This tetradentate set of donor atoms provide selective binding for Am(III) and Nd(III) and yield separation factors of up to 3.7. A continuous liquid liquid extraction and stripping process were performed using Hexaoctyl-NTAamide (HONTA) in n-dodecane as the extractant in a multistage countercurrent mixer-settler extractor. Separation of MA(III) and RE(III) in high yield was demonstrated.
