Title: Ion-exchange Equilibria of Metal Complexes of Chloride with Amberlite IRA-400 Anion-exchanger Resin
Abstract: Ion-exchange equilibria of Fe (II), Mn (II) and Co (II) complexes of chloride on Amberlite IRA 400 Anion-exchanger have been studied by determining distribution number (D) of each complex between aqueous and resin phases as a function of metal ion and ligand (HCl) concentrations. Result of the study shows that increasing the concentration of metal ion (at a constant concentration of ligand) or vice versa resulted in the increase of D values. Analysis of ion exchange process using isotherm Langmuir and stoichiometric equilibria has suggested that the exchange is a complete monolayer adsorption and that the charge of the complex, in this case, does not significantly affect the ion-exchange process.
