Abstract N,N′-dimethyl-N,N′-dihexyl-3-oxapentanediamide, DMDHOPDA, N,N′-dihexyl-3-thiopentanediamide, DHTPDA and N,N′-dihexyl-3-oxapentanediamide, DHOPDA were synthesized and tested for the synergistic extraction of Eu3+, Th4+, UO 2 2+ , NpO 2 + and Am3+ with thenoyltrifluoroacetone (HTTA). Although Eu3+, Th4+, UO 2 2+ and Am3+ were not extracted by DHTPDA or DHOPDA alone, they were extracted synergistically when combined with HTTA. Analysis of the dependency of extraction on pH and extractant concentration indicated that the dominant extracted species were Eu(TTA)3(A), Th(TTA)3(A)(X), UO2(TTA)2(A) and Am(TTA)3(A) (where A is diamide, and X is chloroacetate or ClO 4 − ).
