Abstract: The extraction of dioxouranium(Ⅵ) from nitric acid solution byPhSO(CH2)nSOPh (n=2,3,4,6)-trichloromethane was studied. When the disulfoxide was PhSO(CH2)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.
