摘　　要：研究了铜金属离子印迹聚合物的制备方法,考察了该印迹聚合物的吸附性能.以铜离子为模板,以4-乙烯基吡啶为功能单体,偶氮二异丁腈为引发剂,乙二醇二甲基丙烯酸酯为交联剂进行聚合,聚合产物用盐酸进行洗脱,得到铜离子印迹聚合物.利用红外光谱仪、差示扫描量热仪等,对铜金属离子印迹聚合物的结构进行表征.采用静态和动态法分析研究铜金属离子印迹聚合物的吸附性能和选择性.结果表明,与非印迹聚合物吸附剂相比,铜离子印迹聚合物对铜离子具有较好的选择性识别能力,吸附选择性系数较高,可望在分离富集领域获得实际应用.The preparation and adsorbability of copper ion imprinted polymer is studied. With copper template, 4-vinylpyridine as functional monomer, azodiisobutyronitrile as initiator and etylene glycol dimethacrylateas cross-linkers, polyreaction is done. The copper ion imprinted polymer is attained when washed by hydrochloric acid. The structure of the copper ion imprinted polymer is characterized by IR, TG. The adsorbability and selectivity of the copper ion imprinted polymer is tested by the method of static adsorption and fluidizing adsorption. The results show that the copper ion imprinted polymer has the ability of selective recognition for copper ion in comparison of the non-imprinted polymer and can be applied in the fields of separation and enrichment.
