以红霉素为模板分子、甲基丙烯酸为功能单体、乙二醇二甲基丙烯酸酯为交联剂,采用沉淀聚合法制备了粒径均一的红霉素纳米分子印迹聚合物微球,优化了分子印迹聚合物的合成条件,确定了模板分子与功能单体的最佳摩尔比为1:3,对其进行了表征.结果表明,所制聚合物对红霉素的实际最大吸附量可达202.12mg/g,吸附约200min达到平衡,对红霉素具有良好的选择性吸附能力.
Using erythromycin as a template molecule, methacrylic acid as a functional monomer and ethylene glycol dimethacrylate as a cross-linking agent, a uniform particle size erythromycin nano-molecularly imprinted polymer microsphere was prepared by a precipitation polymerization method. The synthesis conditions of the molecularly imprinted polymer were optimized and the optimum molar ratio of template molecule to functional monomer was 1: 3.The results showed that the optimum adsorption capacity of the polymer to erythromycin Up to 202.12mg / g, adsorption of about 200min to achieve a balance, has a good selective adsorption of erythromycin.
