杀铃脲分子印迹聚合物制备及识别性能的研究

Preparation and properties of triflumuron molecularly imprinted polymer

采用分子印迹技术,以杀铃脲为模板分子,甲基丙烯酸为功能单体,乙二醇二甲基丙烯酸酯为交联剂,在四氢呋喃溶剂中制备了杀铃脲分子印迹聚合物。以平衡吸附及高效液相色谱的方法对聚合物进行了评价。印迹聚合物对模板分子有较强的吸附能力和良好的选择性,可以很好的分离模板分子及其结构类似物。

Molecularly imprinted polymer was synthesized with triflumuron as template molecular, methacrylic acid（MAA） as functional monomer, ethylene dimethacrylate （EDMA） as crosslinker, azobisisobutyro - nitrile （AIBN）as initor. The results showed that imprinted polymer had specific binding affinity for triflumuron. The polymer selectivity was indicated by the separation of triflumuron and its structural analog in the HPLC analysis with the resulting polymer as stationary phase.
