红霉素表面分子印迹聚合物的制备及其吸附性能研究

Abstract

采用表面分子印迹技术，以红霉素(EM)为模板分子，制备红霉素分子印迹聚合物(EM-MIPs)。利用扫描电镜和粒径分析对聚合物进行表征，通过静态吸附平衡实验、 动态吸附实验及选择性实验考察聚合物的吸附性能，结果显示聚合物成功接枝在硅胶表面，EM-MIPs对红霉素具有良好的吸附性能和特异选择识别能力。 This study aims to prepare erythromycin imprinted polymers(EM-MIPs) by surface polymerization method at the surface of modified silica particles by using erythromycin(EM) as the template molecule. The synthesized EM-MIPs were characterized by scanning electron microscope (SEM) and particle size analysis. The results indicated that the MIPs layer has been successfully grafted on the surface of silica particles. The adsorption and recognition properties the obtained polymers were evaluated by static binding test, dynamic binding test and selective binding test. The results showed that EM-MIPs displayed higher recognition ability and adsorption capacity to the template molecule- EM.
