Abstract: A molecular imprinted polymer was prepared by bulk polymerization using pymetrozine as template,methylacrylic acid as monomer,azo- bio( isobutryonitrile) as initiator,ethylene glycol dimethacrylate as cross-linker.The molar ratio of template to monomer was optimized and the synthesized molecular imprinted polymer was characterized by isothermal adsorptions test and adsorption kinetics. The results indicated that the molecular imprinted polymer was 3.0 times of adsorption capacity than that of non- imprinted polymers,and could reach adsorption equilibrium within 80 min at 20 mg / L concentration.The adsorption behavior was studied using pseudosecond- order kinetic model( R2= 0.999) and scatchard analysis and the results showed that the adsorption behavior abeyed pseudo- second- order kinetic model and the polymers with specific imprinted site formed during imprinting proceedings possess the same binding with the targets.
