摘　　要：以邻苯二甲酸丁苄酯作为模板,α-甲基丙烯酸作为功能单体,偶氮二异丁腈作为引发剂,乙二醇二甲基丙烯酸酯作为交联剂,制备了邻苯二甲酸丁苄酯分子印迹聚合物.动力学吸附实验显示:印迹聚合物对模板的吸附5 h达到平衡,平衡吸附和竞争吸附实验显示印迹聚合物比非印迹聚合物对模板的吸附能力更强,对模板的吸附能力优于其它同类分子,表明邻苯二甲酸丁苄酯分子印迹聚合物对邻苯二甲酸丁苄酯分子具有良好的吸附性能和选择性.The molecularly imprinted polymer of butyl benzyl phthalate was prepared by using butyl benzyl phthalate as template,α-methacrylic acid as functional monomer,azodiisobutyronitrile as initiator and ethylene glycol dimethacrylate as crosslinking agent.Kinetic adsorption experiment showed that the adsorption equilibrium time was 5 hours.The equilibrium adsorption and competitive adsorption experiments showed that the adsorption capacity of molecular imprinted polymer was higher than that of non-molecular imprinted polymer,and the adsorption capacity of molecular imprinted polymer on template was larger than its analogue.The results of the experiment demonstrate that the molecular imprinted polymers of butyl benzyl phthalate have good adsorption capacity and selectivity for butyl benzyl phthalate.
