摘　　要：有机磷农药残留是食品安全的重要问题之一,对食品中的有机磷农药进行检测十分迫切必要。然而,食品是一种成分复杂的基质,检测之前必须通过前处理步骤提取和纯化。该文总结了有机磷农药仪器分析的前处理方法,包括固相萃取、液-液微萃取、超声萃取、微波辅助萃取、免疫亲和层析、纳米材料富集等方法,并介绍了这些方法的原理、优缺点以及应用,以期为相关研究提供参考。The residue of organophosphorus pesticide（ OPPs） is one of the most serious problems of food safety in China. It is urgently necessary to determinate the OPPs in foods. However,foods are a kind of complex matrix,and the OPPs must be extracted and purified by pretreatment method. In this work,the novel pretreatment methods of OPPs for instrumental analysis,including solid phase extraction,liquid- liquid microextraction,ultrasonic extraction,microwave assisted extraction,immune chromatography and enrichment by nano-materials etc,were introduced. The principles,advantages,disadvantages and the applications of these methods were introduced. This review provides a reference for related research projects.
