| 摘 要： | 以γ-氨丙基三甲氧基硅烷(AMPS)为硅胶表面改性剂,甲基丙烯酸为功能单体,乙二醇二甲基丙烯酸酯为交联剂,罗红霉素(ROX)为模板分子,制备得到罗红霉素分子印迹硅胶材料(ROX-MIP-PMAA/SiO2),采用红外、扫描电镜和粒径测定等方法对其进行了表征.通过静态和动态吸附实验研究了ROX-MIP-PMAA/SiO2对罗红霉素的吸附性能,并以红霉素为竞争底物,研究其选择吸附性能.结果显示,ROX-MIP-PMAA/SiO2对罗红霉素的吸附能力明显大于非印迹硅胶(NIP-PMAA/SiO2),其对罗红霉素和红霉素的分离因子为1.21,说明其对罗红霉素具有较好的选择吸附性能.

| Abstract: | Roxithromycin molecularly imprinted silica was prepared by using AMPS as the silica surface modifier, methacrylic acid as the functional monomer, ethylene glycol dimethacrylate as the crosslinker, and roxithromycin as the template molecule. Its structure was characterized by infrared spectroscopy, scanning electron microscope and particle size analysis. The adsorption properties of ROX-MIP-PMAA/SiO2 on roxithromycin were studied by static binding test and dynamic binding test, and its selective adsorption properties was investigated by selective binding test with erythromycin as the competing substrate. Results showed that the roxithromycin adsorption capacity of ROX-MIP-PMAA/SiO2 was better than that of NIP-PMAA/SiO2. The separation factor of roxithromycin and erythromycin for ROX-MIP-PMAA/SiO2 was 1.21, showing that ROX-MIP-PMAA/SiO2 displayed high recognition ability to the template molecule. |
