摘　　要：以丙烯酸为聚合单体,TMPTA为交联剂,AIBN为引发剂,咪草烟为模板分子,采用在低温光聚合的方法,制备了对咪草烟分子具有选择性识别能力的分子印迹聚合物.通过IR和HPLC表征,咪草烟分子印迹聚合物对咪草烟分子具有良好的识别作用.A new method for the preparation of imazethapyr molecular imprinted polymer was proposed using low temperature polymerization procedure, with acrylic acid as monomer, TMPTA as crosslinker, AIBN as initiator, and imazethapyr as template dements. The polymer was characterized by IR, NMR spectra as well as HPLC method. The results showed that the molecular imprinted polymer synthesized has a good identification to imazethapyr, and the separation efficiency is as high as 92.3 %.
