O. Box 69(17),Xi′an 710024)Abstract:The synthesis of bifunctional organophosphorus chelating resin(D301-CMP)is reported.The sorption of Am(Ⅲ) and Cm(Ⅲ)on D301-CMP resin is studied.The D301-CMP resin has been characterizated by IR Spectram. The attachment ratio of DHDECMP to the D301 resin is 0.27.It’s property to absorb Am(Ⅲ)and Cm (Ⅲ)under various concentrations of nitric acid is studied.The relationship of distribution coefficient of Am(Ⅲ)and Cm(Ⅲ)on D301-CMP resin to the concentration of nitric acid is rather different from DHDECMP itself but similar to unpurified DHDECMP.Keywords:Dihexyldiethylcarbamoylmethylphosphonate(DHDECMP)Phosphono carbanion Chelating resin Am(Ⅲ)Cm(Ⅲ)
