中文摘要：

利用分子印迹技术制备了重金属铅（Ⅱ）的印迹聚合物,并对其识别性能进行定量描述。以铅（Ⅱ）离子为模板,水杨醛肟为功能单体,二甲基丙烯酸乙二醇酯为交联剂,偶氮二异丁腈为引发剂,采用本体聚合法制备印迹聚合物。结果表明,与未印迹的聚合物相比较,印迹聚合物对铅（Ⅱ）离子具有较好的识别选择性,达到吸附平衡的时间为40min,Pb2＋初始浓度为10mg/L时,最大吸附量为949μg/g,并推测了该印迹聚合物和铅离子的识别机理。

英文摘要：

An ion imprinted polymer（IIP） was prepared by molecular imprinting technology（MIT）.The selectivity and adsorption capacity for Pb（Ⅱ） ions of Pb（Ⅱ）-IIP were studied.The IIP was prepared by bulk polymerization using lead（Ⅱ） ion as a template,salicylaldoxime as a functional monomer and ethylene glycol dimethacrylate（EGDMA） as a crosslinker.The results showed that,in comparison with non-imprinted polymer,the sorption equilibrium was achieved in 40 min and the maximum sorption of lead（Ⅱ） imprinted polymer was about 949μg/g by Pb2＋ was 10 mg/L.The mechanism for the adsorption of Pb（Ⅱ） on the imprinted polymers was investigated.
