| Abstract: | This paper reported a synergistic extraction of Ho 3+ with binary systems containing HPMBP and diphenyl-guanidine(DPG) using chloroform as diluent from nitric acid medium.The results indicated that there was obvious positive synergistic extraction effect in this system.The composition of the extraction complex was proved,by means of Slope Analysis,to be HB] +HoA 4] -,where HA=HPMBP and B=DPG.The extraction equilibrium constant was K=27.24.Furthermore,the synergistic extraction mechanism and the structure of complex were discussed. |
