摘　　要：除草剂是指能够消灭杂草而又不影响农作物生长的一类药剂,在农业生产活动中应用极为广泛.除草剂种类繁多,其使用虽然给人类带来了许多益处,但也对人类的身体健康造成了一定的威胁,除草剂投毒或中毒事件时有发生.目前,对于复杂基质中性质各异的除草剂检测存在诸多挑战.作为一种新型样品预处理技术,磁性固相萃取技术以操作简便、吸附能力强、成本低等优势被广泛应用于诸多领域.磁性固相萃取技术与现代分析方法结合,在环境分析、药物分析、食品卫生等领域的应用也越来越广泛.在简述磁性固相萃取技术基本原理和特点的基础上,着重综述了磁性固相萃取技术在检测环境、农产品和生物样品等基质中各类除草剂的应用研究进展,以期在展望磁性固相萃取技术未来的研究重点和发展趋势的同时,拓展其在法庭科学物证鉴定领域中的应用,为我国司法鉴定提供技术参考.Herbicides are a class of agents that can destroy weeds without affecting the growth of crops,and are widely used in agricultural activities.There are many types of herbicides,while their use has brought many benefits to humans,and also pose a threat to human health.The incidents of herbicides poisoning or poisoning occur from time to time.Currently,there are many challenges in the detection of herbicides with different properties in complex matrices.As a new kind of sample pretreatment technique,magnetic solid-phase extraction(MSPE)is widely used in many fields due to the advantages of easy operation,strong adsorption capacity and low cost.MSPE combined with other modern analytical methods,is also widely used in the fields of environmental analysis,drug analysis,food hygiene and etc.The basic principles and characteristics of MSPE were described briefly.The applications of MSPE in the detection of various types of herbicides in environmental samples,agricultural products and biological samples were discussed in details,aiming to look forward to the future focus of the research and development trend of MSPE.And the applications of MSPE in forensic identifications were expanded to provide a technical reference for the judicial expertise of our country.
