With micro-porous silica functioned with 3-(trimethoxysilyl) propyl methacrylate reagent as carrier,a kind of novel molecularly imprinted polymer bound on silica surface was synthesized by using MAA and quinine as functional monomer and template respectively.The polymer was characterized by IR and SEM.MAA and quinine could interact to form super-molecular complexes,which were confirmed by fluorescence and UV spectroscopy.The adsorption properties of the polymers toward substrates were evaluated by equilibrium adsorptive experiments.The results show that there exist distinct difference between the template polymer and the control polymer,the maximum special adsorption amount toward template is 36.40 μmol/g.The separation factor reaches 1.64 for quinine and cinchonine.
