摘　　要：磺酰脲类除草剂本身易降解,在环境和生物样品中痕量存在,其残留分析工作颇具挑战。分子印迹聚合物因良好的选择性和稳定性已被广泛应用于农药残留分析的分离与富集前处理过程,提高了检测的准确度和精密度。本文从单体、溶剂与致孔剂、聚合方法三个方面概述了近15年来磺酰脲类分子印迹聚合物的制备,并对其在残留检测中的应用进行了综述,为磺酰脲类除草剂残留检测技术的进一步开发提供参考。Sulfonylurea compounds are susceptible to degradation and exist in environmental and biological samples at trace level. It is a great challenge to detect sulfonylurea hebicides. Molecularly imprinted polymers（ MIPs） have charateristics of high selectivity and chemical stability. Thus,as a separation and enrichment medium,MIPs have been widely applied in the determination of pesticide residues to improve the accuracy and precision of analytical results. In this paper,the syntheses of sulfonylurea-MIPs for recent 15 years were reviewed according to the following three aspects： monomer,solvent and polymerization method. Moreover,the applications of sulfonylureaMIPs in residue detection were summarized. It is hoped that this review will provide a reference for detection technology research of sulfonylurea herbicides residues.
