| Abstract: | The mechanisms of extracting Am3 and Gd3 in 0.05 mol/L HNO35.0 mol/L NaNO3 solution by TBPkerosene, DHDECMPkerosene and DHDECMPTBPkerosene have been studied. There exists synergism in the extraction of Am3 or Gd3 with DHDECMPTBPkerosene. The solvates are Am(NO3)33TBP,Am(NO3)33CMP,Gd(NO3)33TBP, and Gd(NO3)33CMP, respectively. The solvates in synergistic extraction are Am(NO3)33CMPTBP and Gd(NO3)32CMPTBP, respectively.The equilibrium constants K and thermadymic constants HG and S have been measured. The value of KGH and S of synergistic extraction of Am3 is8.2103L7mol-7,-27kJ/mol,-23 kJ/mol,-13 J/molK and of Gd3 is 6.3102 L6mol-6,-31 kJ/mol,-16 kJ/mol,-50 J/molK, respectively. |
