摘　　要：采用分子印迹技术,以壳聚糖为聚合物基体,敌百虫为模板分子,制备在空间结构和结合位点上与敌百虫匹配的分子印迹聚合物.研究该聚合物的合成条件,包括壳聚糖与敌百虫的作用力,以及交联、洗脱条件.测定分子印迹聚合物对敌百虫的吸附和选择识别能力,并对其结构进行表征.结果表明,所合成的分子印迹聚合物对敌百虫具有良好的吸附和选择识别能力,其中对结构类似的氧化乐果的分离系数达到3.57.Using chitosan as a polymer matrix, trichlorfon as a template molecule, we prepared trmhlorlon motecutarly imprinted polymers （Tri-MIPs） that match up with template molecules in space structure and the binding sites by molecularly imprinting technique. The synthesis of the Tri-MlPs, including the forces between chitosan and trichlorfon, as well as crosslinking and etution conditions was investigated. In addition the absorption and selective recognition ability of Tri- MIPs to trichlorfon was studied and its structure was charicterized. The result shows that the Tri-MlPs have good capacities of both absorption and selection. The separation factor to omethoate which has a similar structure with trichlorfon reached 3.57.
