| Abstract: | Using kerosene and 40%(v)n octanol as diluents,some lanthanide and actinide can be extracted effectively by amido podand from nitric acid solutions.The effects of the concentrations of the nitric acid in aqueous phase and the structure of amido podands on distribution ratios were examined.Under the same nitric acid concentration conditions,the extractive capability of amido podands with different structure was compared.The extractive capability of asymmetric amine is higher than that of symmetric amine. |
