Cation exchange effective equilibrium distribution coefficients(K'd) of 18 metal ions with resin Amberlite IR-120 have been determined in varying adipic acid [&#181;2AA] concentrations, viz., 2.0×10<SUP>-2</SUP> _ 7.6×10<SUP>-2</SUP> M [H2AA]. Separation factors of metal ion species were calculated and some possible binary separations were worked out on the basis of their K'd values. An entirely different approach has been proposed for the association of adipate anion involving its partial exchange with the resin site along the complexation of the metal species.

Abstract


Cation exchange effective equilibrium distribution coefficients(K'd) of 18 metal ions with resin Amberlite IR-120 have been determined in varying adipic acid [&#181;2AA] concentrations, viz., 2.0×10<SUP>-2</SUP> _ 7.6×10<SUP>-2</SUP> M [H2AA]. Separation factors of metal ion species were calculated and some possible binary separations were worked out on the basis of their K'd values. An entirely different approach has been proposed for the association of adipate anion involving its partial exchange with the resin site along the complexation of the metal species.
