摘要：

The diamide type extractants (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 extraction of the lanthanide and actinide elements. The elements, Eu3+, Am3+, Th4+, NpO2+ and UO22+, when extracted by DMDHOPDA, showed no pH-dependence. The relationships between log[DMDHOPDA] and log D under different ionic strengths were investigated in order to clarify the extraction reactions. The separation factor for Eu3+/Am3+ is 8.64.
