食品基质有机磷农药残留的前处理新方法研究进展

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。

Novel Pretreatment Methods for the Determination of Organophosphorus Pesticides in Foods

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.
