Preparation of omethoate imprinted polymer and its application

ZHENG Hong,HU Li-mei*(Department of Chemistry,Chongqing Normal University,Chongqing,401331,China)  
A molecularly imprinted polymer was prepared by in situ step-addition polymerization using omethoate as the template.The characteristics of selective separation and preconcentration for omethoate,dichlorovos and methamidophos were tested on the polymer.The omethoate in the honey,vegetable and natural water was extracted via using the polymer.The results indicated that different kinds of recognition sites in the MIPs showed specific affinity toward omethoate.The velocity is 1.0 mL/min,the sampling volume of 20 μL.
【Key Words】: molecularly imprinted polymers omethoate high-performance liquid chromatography
