摘要: Abstract A macroporous polymeric resin, Amberlite XAD-1160, functionalized with −NO2(electron-acceptor) and −NH2(electron-donor) groups to prepare two new functional resins, NO2-XAD-1160 NH2-XAD-1160 respectively, three novel extractant-impregnated resins (EIRs) were prepared by impregnating vesuvin, as an advantageous extractant. The sorption efficiencies of both VSV/NO2-XAD-1160 VSV/NH2-XAD-1160 towards Pb(II) ion compared those conventional VSV/XAD-1160 gain insight about the effects on kinetics, equilibrium, thermodynamic other properties. Comparative studies showed that benefits for using in full-scale treatment processes are more than VSV/NH2-XAD-1160.
