%X The synergistic extraction of Cd(Ⅱ)with primary amine N-1923 and neutralorganophosphorus reagents(TBP,DBBP,B)from hydrochloric acid has been investigated atμ=0.5,t=25℃.The compositions of the synergistic extraction complexes and the mechanismof the synergistic extraction have been determined by the methods of slope and constant mole.The synergistic extraction complexes with composition(RNH_3Cl)_2·CdCl_2·B have beendemonstrated.The synergistic extraction reactions and additional reaction of Cd(Ⅱ)havebeen proposed as follows:CdCl_2+2RNH_3Cl_(o)+B_(o)(RNH_3Cl)_2·CdCl_2·B_(o)(RNH_3Cl)_3·CdCl_(2(o)+B_(o)(RNH_3Cl)_2·CdCl_2·B_(o)+RNH_3Cl_(o)In addition,the equilibrium constants and the thermodynamic functions of the synergistic ex-traction reactions have been calculated.The IR and NMR spectra of the synergistic ext-ac-tion complexes of Cd(Ⅱ)have been studied as well.
