摘要
利用甲苯的致孔效应，以甲苯作为模板分子，以甲基丙烯酸和二乙烯基苯分别作为功能单体和交联剂，采用沉淀聚合法合成了甲苯分子印迹聚合物。静态平衡吸附实验结果表明，所得到的印迹聚合物对甲苯具有较强的选择性吸附能力，最大吸附容量为21．6mg／g。将所制备的印迹材料作为固相荤取填料，对自来水样品中的甲苯进行选择性分离富集，加标回收率在92％～103％之间。
A molecularly imprinted polymer （MIP） for toluene was synthesized by precipitation polymerization using toluene as porogenic template, methacrylic acid as functional monomer and divinylbenzene as crosslinker. The recognition abilities of the obtained MIP and control polymer were investigated by the classical steady-state binding method. Experiments showed that the imprinted polymer exhibited a much higher capacity than that of the control polymer for binding to toluene The maximum amount bound by the MIP was 21.6 mg/g. The proposed MIP was successfully applied to the enrichment of toluene in tap water samples with recoveries ranging from 92 % to 103 %.
