摘　　要：A series of disulfoxides which have not been reported previously were synthesized by oxidation of sulfide with nitric acid and characterized by elemental analysis,IR and NMR spectroscopy.Microcapsules(MC) containing tri n butyl phosphate(TBP) and disulfoxides were prepared by interface condensation polymerization,and uranyl in aquous solution were extraced with the MC.The results show that extracting abilities of disulfoxides for uranyl are superior to that of TBP,and that of di (phenyl sulphinyl) ethan is the best one among them.A series of disulfoxides which have not been reported previously were synthesized by oxidation of sulfide with nitric acid and characterized by elemental analysis,IR and NMR spectroscopy.Microcapsules(MC) containing tri n butyl phosphate(TBP) and disulfoxides were prepared by interface condensation polymerization,and uranyl in aquous solution were extraced with the MC.The results show that extracting abilities of disulfoxides for uranyl are superior to that of TBP,and that of di (phenyl sulphinyl) ethan is the best one among them.
