Abstract: In this study, surface imprinted particles were synthesized by precipitation polymerization using silica microspheres as carrier for adsorbing sulphamethoxazole (SMO) from aqueous media. Different functional monomers (4-vinylpyridine, acrylamide and methacrylic acid) and different cross-linkers (ethylene glycol dimethacrylate and N, N'-methylenebisacrylamide) were selected to synthesize different kinds of molecularly imprinted polymers (MIPs) and their corresponding non-imprinted polymers. The MIP with the best adsorption performance in aqueous media was identified by adsorption experiments. Various kinds of kinetic models and isotherm models were fitted, and the kinetic and isotherm properties of MIPs in selective adsorption were studied and analyzed in depth. Advanced characterization methods were applied to demonstrate the successful preparation of the imprinted materials, and expound their physical and chemical properties. In addition, the concentration of SMO in aqueous media was determined by solid-phase extraction and high-performance liquid chromatography
