Abstract: The uniform-sized spherical molecularly imprinted polymers were successfully prepared through molecular imprinting technology by two-step seed swelling and miniemulsion polymerization in the aqueous condition using quinine molecules as templates and methacrylic acid (MAA) as functional monomers. The polymers were characterized by IR spectra, thermal-weight analysis, scanning electron microscope and laser particle size analysis. The adsorption amounts of the polymers varied when the solution for absorption changed. The results indicated that the interaction between acidic monomer/polymer and template with amino group mainly depended on hydrogen bonding and ionic (electrostatic) interaction. And their recognizing mechanism altered as the type of the solvent changed. The experiments of binding different substrates indicated that the MIPs possessed an excellent rebing ability and inherent selectivity to quinine
