Popis: | The extraction of uranyl nitrate with the novel extractant N,N′-dimethyl-N,N′-dioctylmalonamide (DMDOMA) from aqueous sodium nitrate (and nitric acid) was investigated. The extraction mechanism was established and the stoichiometry of the main extracted species confirms to UO2(NO3)2 · DMDOMA. The IR spectral study was also made of the extracted species. Methyl substituent improves the extraction ability of malonamide for U(VI) compared with that of N,N,N′,N′-tertrabutylmalonamide (TBMA). |
