摘要：

We have studied the extraction of Eu(III), Am(III), Th(TV), U(VI) and Np(V) by 4 diamides (DMDHOPDA, N,N'-dimethyl-N,N'-dihexyl-3-oxapentanediamide; DHOPDA, N,N'-dihexyl-3-oxapentanediamide; DMDHTPDA, N,N'-dimethyl-N,N'-dihexyl-3-thiopentanediamide; DHTPDA, N,N'-dihexyl-3-thiopentanediamide) from perchlorate solutions. Synergistic extraction was observed with these diamides and thenoyltrifluoroacetone (TTA) in which the main extraction species determined are M(TTA)(3)(DA) (M=Eu, Am), Th(TTA)(3)(DA)(X), UO2(TTA)(2)(DA) (DA: diamide, X-: ClO4- or CH2ClCOO-). The species, M(DA)(3)(X)(3), M(DA)(3)(TTA)(X)(2) M(DA)(2)(TTA)(2)(X) and M(DA)(TTA)(3) are observed in the synergistic extraction of DMDHOPDA+TTA. (C) 1998 Elsevier Science S.A.
