摘　　要：吗啡啉通过与酰氯反应合成新型取代酰胺类萃取剂N 辛酰吗啡啉(OMPHL),并对该萃取剂萃取铀时在水相硝酸浓度,萃取剂浓度,温度,盐析剂浓度多种条件下对铀(Ⅵ)的分配比影响进行了研究。A new kind of amide extractant Noctyl acylmopholine (OMPHL) has been prepared at the first time and it's extraction performance to U(Ⅵ) has been tested.The depndence of Du on aqueous nitric acid concentration,on the concentration of extractant,temperature,and saltingout agent has been determined.The UtoOMPHL ratio of the composition of the extracted species probably are 1∶1 and 1∶2.
