Abstract: The extraction of uranium from high level liquid waste is important. In this paper, a series of structural related asymmetric amide extractant bearing methyl on N atom, such as N-methyl-N-decyloctanamide (MDOA), N-methyl-N-decyl-decanamide (MDDA) and N-methyl-N-decyldodecanamide (MDDOA) was designed and synthesized. The extraction thermodynamics of U(Ⅵ) from nitric acid solutions with the aforementioned extractants in n-octane was investigated in detail and the various factors affected extraction properties were studied. |
Keywords: uranium extraction alkylamide n-octane |
