The effect of weakly basic resins (D301G, D301R), strongly basic resin (201×4 ) and porous resin (D4020) on sorption equilibrium was evaluated. The monocomponent sorption equilibrium was correlated with general equilibrium isotherm. The correlation results were in good agreement with experimental ones. Based on these isotherms and material balances, two-component competitive sorption isotherms could be successfully predicted by monocomponent equilibrium sorption isotherm parameters. The effect of pH on two-component equilibrium uptake was systematically investigated.展开更多
