High-performance alkyl diamide amine and water-soluble diamide ligand for separating of Am(III) from Cm(III)

Suzuki, Hideya; Tsubata, Yasuhiro   ; Matsumura, Tatsuro  

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.
