中文摘要：

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．

英文摘要：

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.
