Abstract: Two diglycolamide homologs, N,N,N′,N′-tetraoctyl-3,6-dioxaoctane diamide (DOODA) and N,N,N′,N′-tetraoctyl-3,6,9-trioxaundecane diamide (TOUDA), were synthesized. Their extraction behaviors of Am3+ and Eu3+ were investigated and compared with those of N,N,N′,N′-tetraoctyl-3-oxapentane diamide (TODGA). The extraction ability toward Am3+ and Eu3+… read more here.

Abstract: Diglycolamides (DGAs), and in particular N,N,N′,N′-tetraoctyl diglycolamide (TODGA), are well-known candidates for the co-extraction of trivalent actinides (An(III)) and lanthanides (Ln(III)) from highly acidic aqueous solutions of nuclear waste. A derivative of TODGA, the so-called… read more here.
