中文摘要:

      农产品中常用的农药包括有机磷、氨基甲酸酯、拟除虫菊酯、有机氯和新烟碱类, 然而农药的高毒性对消费者造成潜在的健康危害。在农药残留分析方法建立过程中开发和使用具有“绿色化学”特点的溶剂和方法一直是分析工作者努力的方向。QuEChERS技术中基质净化步骤在农药残留分析中起着至关重要的作用。本文综述了QuEChERS样品制备方法在水果蔬菜等农药残留检测中的应用概况, 总结了QuEChERS技术常用的传统净化材料如N-丙基乙二胺和石墨化炭黑、十八烷基键合硅胶固定相和新型净化材料如多壁碳纳米管、磁性纳米材料、氟化材料及其他新型改性材料等在农药残留检测中的应用进展, 就新型净化材料的结构特性、功能及应用进行了分析, 阐明了QuEChERS技术的发展趋势和前景在于开发更多操作便捷、成本低廉的新型净化材料, 有助于这一领域进一步的研究发展。

英文摘要:

      Pesticides from the classes of organophosphates, carbamates, pyrethroids, organochlorines and neonicotinoids have been commonly used in agricultural products. However, the high toxicity of pesticides poses a potential health hazard to consumers. Developing and using solvents and methods with the characteristics of “green chemistry” in the process of establishing methods for pesticide residue analysis has always been the direction of the efforts of analysts. The clean-up steps in QuEChERS technology play a critical role in the success of pesticide residue analysis. This paper reviewed the application progress of QuEChERS sample preparation methods in the detection of pesticide residues of fruits and vegetables, summarized the application progress of traditional purification materials commonly used in QuEChERS technique, such as N-propyl ethylenediamine and graphitized carbon black, octadecyl bonded silica gel fixed phase and new purification materials, such as multi-wall carbon nanotubes, magnetic nanomaterials, fluorinated materials and other new modified materials, in pesticide residue detection, analyzed the structural characteristics, functions and applications of the new purification materials, and clarified that the development trend and prospect of QuEChERS technology lied in the development of more convenient and low-cost new purification materials, which is conducive to further research and development in this field.
