摘要
采用分子印迹技术,以α 甲基丙烯酸(MMA)为功能单体,乙二醇二甲基丙烯酸酯(EGDMA)为交联剂,合成出以潘生丁为模板的印迹聚合物。研究了原料配比、预/聚反应时间对产物洗脱效率的影响.结果表明,当潘生丁,MMA,EGDMA的摩尔比为1∶8∶80时得到的产物洗脱效率最高.对其吸附效率和选择性进行了表征,与化学组成相同的空白聚合物相比,印迹聚合物具有更高的吸附效率和选择性.按最佳合成条件得到的印迹聚合物吸附量达26.85μmol/g,为理论吸附量的49.7%.
The molecularly imprinted polymer with persantin as template molecule was prepared by molecular imprinting technique using α-methacrylic acid as a functional monomer and EGDMA as a cross-linker. The influence factors for elution efficiency, such as raw material ratios, fore-reaction time and reaction time etc are discussed in detail. The results show that the polymer has the highest elution efficiency when raw material mole ratios(n(Persantin)∶n(MMA)∶n(EGDMA)) was 1∶8∶80; The adsorption efficiency and selectivity were investigated, the imprinted polymer had higher adsorption efficiency and higher selectivity compared to the blank polymer which had the same chemical composition; The adsorption (amount) of the best imprinted polymer was to be 26.85 μmol/g which therefore correspond to 49.7% of the theoretical amount.
