dc.description.abstractThe Pb2+-imprinted (PHEMAC-Pb2+)particles were prepared by bulk polymerization as a solid-phase extraction (SPE) adsorbent. N-methacryloyl-(L)-cysteine (MAC) was used as functional monomer to have a well-shaped molecular geometry between MAC monomer and Pb2+ ions that provide molecular recognition based on well fitted cavities for Pb2+ ions after removal of template ions. The PHEMAC-Pb2+ particles were characterized and the applicability of these particles was investigated for the solid-phase extraction of Pb2+ ions from aqueous solutions and environmental samples. The PHEMAC-Pb2+ particles with a size range of 50-200 mu m have a rough surface and macropores in bulk structure. The adsorption capacity of the PHEMAC-Pb2+ particles is relatively low (2.01 mg/g). However, the high selectivity towards competitive ions (Cd2+, Ni2+ and Cu2+) promises the PHEMAC-Pb2+ particles an alternative SPE adsorbent in literature. The relative selectivity coefficients of PHEMAC-Pb2+ particles for Pb2+/Ni2+, Pb2+/Cd2+ and Pb2+/Cu2+ were almost 71, 117 and 192 times greater than that of non-imprinted (PHEMAC) particles, respectively. Moreover, the reusability of the PHEMAC-Pb2+ particles was tested for several times and no significant loss in adsorption capacity was observed. The accuracy of the proposed procedure was also verified by the determination of Pb2+ ions in the certified reference material, LGC 6137 Estuarine sediment. (C) 2009 Elsevier B.V.
