Abstract
- A macroporous polymeric resin, Amberlite XAD-1160, functionalized with −NO 2 (electron-acceptor) and −NH 2 (electron-donor) groups to prepare two new functional macroporous resins, NO 2 -XAD-1160 and NH 2 -XAD-1160 respectively, and three novel extractant-impregnated resins (EIRs) were prepared by impregnating XAD-1160, NO 2 -XAD-1160 and NH 2 -XAD-1160 with vesuvin, as an advantageous extractant. The sorption efficiencies of both VSV/NO 2 -XAD-1160 and VSV/NH 2 -XAD-1160 towards Pb(II) ion were compared with those of conventional VSV/XAD-1160 to gain insight about the effects of functional groups on the kinetics, equilibrium, thermodynamic and other sorption properties. Comparative studies showed that VSV/NO 2 -XAD-1160 benefits for using in full-scale treatment processes are more than those of VSV/XAD-1160 and VSV/NH 2 -XAD-1160. [ABSTRACT FROM AUTHOR]
