摘要
目的应用气相色谱质谱联用技术检测茶叶中多种拟除虫菊酯类农药。方法用振荡器和样品浓缩仪优化样品前提取方法,以气质联用仪分析菊酯类农药。结果该方法相对标准偏差在2.77%～5.35%之间,回收率在80.4%～93.6%之间,线性相关系数大于0.9989。结论本方法准确可靠,可应用于茶叶中等多种拟除虫菊酯类农药的测定。
Aim To determine pyrethroid pestcide in tea leaf by gas chromatography mass spectrometry. Methods Gas chromatography mass spectrometry was used for determination of pyrethroid pestcide in tea leaf. Results The relative standard deviations were 2.77%-5.35% and the recoveries were 80.4%-93.6% .The correlation coefficients for the linear equation was 09989-0.9996. Conclusion The results mentioned above indicated that the method was accurate in determination of pyrethroid pestcide in tea leaf
