中文摘要:

      农药残留事关环境污染、食品安全等系列问题, 而样品处理是整个分析检测过程中关键的一环, 建立可靠安全的农药检测前处理技术则具有深远意义。QuEChERS (quick, easy, cheap, effective, rugged and safe)作为一种农药残留分析过程前处理方法, 基于其快速、简单、廉价及高效的特点广泛应用于测试分析领域。本文基于6种常见的农药残留前处理技术对比分析的基础上, 选取QuEChERS作为讨论对象, 分析研究QuEChERS方法中涉及的提取剂、分析保护剂、净化剂等材料的选用及配比优化对提高前处理效能的影响, 并综述以QuEChERS方法为手段联用不同色谱、质谱分析技术在农药残留检验方面的应用情况; 针对QuEChERS技术在实际应用过程中所面临的困扰, 进一步探讨新型净化材料在改进QuEChERS方法方面的开发前景, 以期为拓展该前处理技术提供进一步的技术参考。

英文摘要:

      Pesticide residues are related to a series of problems such as environmental pollution and food safety, and sample processing is a key to the whole process of analysis and detection, so it is of far-reaching significance to establish reliable and safe pretreatment technology for pesticide detection. As a pre-treatment method for pesticide residue analysis, QuEChERS, which stands for “quick, easy, cheap, effective, rugged and safe”, is widely used in the field of test analysis because of its fast, simple, cheap and efficient characteristics. Based on the comparative analysis of six common pre-treatment technologies for pesticide residues, QuEChERS is selected as the discussion object in this paper, and the effects of the selection and ratio optimization of materials such as extractant, analytical protectant and purifying agent involved in the QuEChERS method on improving the pre-treatment efficiency isanalyzed. And the application of QuEChERS method combined with different chromatography and mass spectrometry techniques in pesticide residue detection was reviewed. Furthermore, in view of the problems faced by QuEChERS technology in practical application, the development prospect of new purification materials in improving QuEChERS method is further discussed, in order to provide further technical reference for improving and expanding the pre-treatment technology.
