烟草中拟除虫菊酯类农药残留分析技术研究进展

Research progress on analytical methods for pyrethroid pesticide residue analysis in tobacco

  • 摘要: 为方便相关研究人员了解烟草中拟除虫菊酯类农药残留的分析方法,对近年来烟草中拟除虫菊酯类农药的检测方法进行了文献调研和系统总结。结果表明:①目前对此类农药残留分析技术的研究主要集中在样品前处理技术、分析仪器的选择和分析条件的优化方面。②样品前处理技术方面,QuEChERS提取结合多元SPE小柱净化进行烟草样品的前处理,在采用多种分析仪器的检测中均表现出良好的效果。③气相色谱法是目前普遍采用的分析方法,方法的灵敏度高,但干扰相对较多;气相色谱-串联质谱法是主要的发展方向,灵敏度高,干扰少,但仪器价格较高;其他新兴分析方法也具有较好的应用前景。

     

    Abstract: In order to survey available analytical methods for pyrethroid pesticide residue analysis in tobacco, recent literature on pyrethroid pesticides were reviewed and systematic summarized. The results showed that: 1) The current methods mainly focused on sample pretreatment technologies, selection of analytical instruments and optimization of analytical conditions. 2) In terms of sample pretreatment techniques, the QuEChERS extraction combined with SPE column purification presented satisfactory results in the determination with various analytical instruments. 3) Gas chromatography was a universal analytical method with higher sensitivity but prone to interference. Gas chromatography-tandem mass spectrometry has been the main development direction with higher sensitivity and less interference. However, it is relatively expensive. Some other newly-developed analytical methods also have promising applications.
