摘要/Abstract

摘要： 利用分子印迹技术的特异性识别,采用本体热聚合,以酸碱相互作用为基本作用机理,分别以甲基丙烯酸二甲氨基乙酯(DMAEMA)、甲基丙烯酸二乙氨基乙酯(DEAM)、甲基丙烯酸-2-氨基乙基酯盐酸盐(AMA盐酸盐)、4-乙烯基吡啶(4-VP)和甲基丙烯酸(MAA)为功能单体,乙二醇二甲基丙烯酸酯(EGDMA)和二乙烯基苯(DVB)为交联剂,偶氮二异丁腈(AIBN)为引发剂,乙腈为溶剂设计合成了三氯生(TCS)的分子印迹聚合物(MIPs)。吸附结果表明,其中DEAM是TCS的最佳功能单体,吸附率达到了78.5%,印迹因子达到了1.7,用DEAM作为功能单体合成的MIPs对TCS的选择性实验结果显示,对TCS的吸附容量明显高于其结构类似物,对TCS的吸附实验结果显示,5次回收后重复利用,吸附容量仅降低了5.1%,表明该MIPs可以重复使用多次。

Abstract: The working mechanism of molecularly imprinted polymers (MIPs) for triclosan (TCS) is based on acid-base interaction.The designed MIPs were prepared by thermal bulk polymerization using DMAEMA,DEAM,hydrochloride of AMA,4-VP and MAA as functional monomers,EGDMA and DVB as cross-linkers,AIBN as initiator and acetonitrile as solvent.Adsorption study shows that the MIPs made with DEAM achieve highest adsorption percentage of 78.5% and imprinting factor of 1.7.The selective binding experiments show that DEAM-MIPs show high selectivity to TCS over other structural analogues.Adsorption experiments on TCS by MIPs show that after 5 times of recovery,the adsorption capacity only drops by 5.1%,indicating that the MIPs can be reused multiple times.
