摘　　要：研究了PhSO(CH2 ) nSOPh(n =2、3、4、6 ) -三氯甲烷体系从硝酸介质中萃取铀的行为。n=2的双亚砜在萃取时出现三相 ,n =3、4、6的三种双亚砜对铀的萃取规律类似于TBP ,萃取性能略优于TBP。铀的溶剂化数均为 1。The extraction of dioxouranium(Ⅵ) from nitric acid solution by PhSO(CH 2) nSOPh ( n =2,3,4,6)-trichloromethane was studied. When the disulfoxide was PhSO(CH 2) 2SOPh, the third phase formed. The extraction laws of dioxouranium(Ⅵ) by the disulfoxides ( n =3,4,6) were similar to that by tributyl-phosphate(TBP). Their extracting ability was slightly better than that of TBP.
