中文摘要： 为了筛选出一个灵敏、有特异性、简单、快速、低成本、高效率、可靠地复杂基质多残留分析方法，本文提出了一个复杂基质多残留分析策略，并以韭菜为例进行实证研究。本文采用简单薄层色谱法评估清理效果，结果显示效果良好。化合物回收率达到91%，在70-120%范围内，检测限和定量限范围分别为0.1-3.5 ng/g和0.4-11.5 ng/g。该策略可在不同农产品基质多种农药残留或不同化学品分析方法的选择方面提供技术指导。
外文摘要：In order to choose a sensitive, selective, simple, rapid, cost–effective and reliable analytical method for a given complex sample, a strategy was proposed for the evaluation of an analytical approach to determining multi-pesticide residue in complex agricultural product matrices, using leek as an example. In this work, the matrix effect of most of pesticides were in the range of –50 %～–90 %. A simple thin layer chromatography(TLC) was used to evaluate the effect of cleanup. The results agree well with that of matrix effect decribed above. More than 91 % of the investigated compounds achieved recoveries were in the range of 70-120 %. The limits of detection and limits of quantification were in the range of 0.1-3.5 ng/g and 0.4-11.5 ng/g, respectively. The strategy can be used to analyze multi-pesticide residue or related chemicals in diverse agricultural product matrices to provide technical guidance in choosing an analytical approach.
