Article Preview

A novel ion-imprinted organic-inorganic hybrid sorbent was synthesized and characterized by FT-IR and nitrogen gas adsorption-desorption. The adsorption property and selective recognition ability of the imprinted sorbents for the lead ion were studied. Results showed that the uptake capacities and selectivity coefficients of the double imprinted sorbent were much higher than that of the non-imprinted sorbent. The adsorption capacity of the double imprinted sorbent is 545.6 mg•g-1. The largest relative selectivity coefficient between Pb (II) and Cd (II) was 192. This results suggested that the new sorbent can be used as effective solid-phase material for the selective preconcentration and separation of Pb (II) in environmental water samples.
