Abstract 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, $Eu^{3+},$ $Am^{3+},$ $Th^{4+},$ $NpO_{2}^{+}$ and $UO_{2}^{2+},$ 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 $Eu^{3+}/Am^{3+}$ is 8.64.
