Abstract: A novel imprinted polymers based on the surface-modified silica gel was prepared with surface imprinting technique by using Sudan I as template molecule,phenyltrimethoxysilane(PTMOS) as a functional monomer,ethyleneglycol dimethacrylate(EGDMA) as cross-linkers and azodiisobutyronitrile(AIBN) as initiator.The characterization of the core-shell imprinted polymer was investigated by infrared spectroscopy(IR) and scanning electron microscopy(SEM),and the shell thickness of the core-shell imprinted microspheres was obtained to be 150 nm.The MIPs binding performance to the template molecule was also discussed by static adsorption experiment and Scatchard analysis.The results showed that the separation factor was 2.62.Two kinds of binding sites existed between the core-shell imprinted polymers and the template(Sudan I).Their Kd were 2.30 and 10.78 mmol/L,respectively,and Qmax were 27.40 and 128.53 μmol/g,respectively.Combining with high performance liquid chromatographic(HPLC) method,the core-shell imprinted polymers used as solid extraction materials were successfully applied to detect Sudan I in chili oil sample.
