Abstract: Pb(II) Ion Imprinted Magnetic Composite Adsorbent (Pb(II)-MICA) was prepared for the quick separation of Pb(II) from aqueous solutions by bulk polymenrization with chitosan as the functional monomer, the magnetic iron oxide nano-particles as carrier and epichlorohydrin as the cross-link agent. The Pb(II)-MICA and MNICA were characterized by FTIR. The Effects of the adsorption process including pH, contact time, initial concentration and temperature were investigated by FAAS. It was found that with the increasing of PH value, the adsorption capacity of Pb(II)-MICA for Pb(II) reached the peak in the range of pH 5.0~6.0. The maximum adsorption capacity was 32.48 mg g-1 when the adsorption time was up to 120 min. The relative selectivity coefficient of Pb(II) and other metal ion on Pb(II) -MICA were 28.11, 91.14, 76.54, 33.06 times compared with MNICA. The results show that the Pb(II)-MICA displayed strong affinity for Pb(II) in the solution and exhibited selectivity for Pb(II) ion in the presence of Cu2+,Cd2+,Ni2+ and Zn2+. The Langmuir adsorption isotherm models were fit to the adsorption equilibrium data well (r2=1, the saturation adsorption capacities were 33.87 mg g-1). The adsorption dynamics and thermodynamics of Pb(II) -MICA for Pb(II) were investigated, the results indicated a Langmuir mono-layer mode process of Pb(II) on the Pb(II)-MICA was dominated by chemical action. An exothermic and spontaneous adsorption process of Pb(II) on the Pb(II)-MICA was driven by enthalpy.
