摘　　要：以酰胺荚醚为萃取剂 ,正辛醇和煤油的混合物作稀释剂 ,研究了水相硝酸浓度和不同结构酰胺荚醚对镧系和锕系元素萃取分配比的影响 ,并对它们的萃取性能进行了比较 ,结果表明 。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.
