中文摘要:

      目的 改进韭菜中阿维菌素农残分析方法。方法 采用乙腈提取韭菜中的阿维菌素, 用氨基柱对样品进行净化, 利用液相色谱作为检测手段, 紫外检测器进行定性定量分析。结果 这种前处理方法经过氨基柱的回收率在98.11%~102.23%, 相对标准偏差为5.31%~6.76%, 最低检出限为0.01 mg/kg。结论 韭菜中阿维菌素的残留检测操作简单、灵敏度高、添加回收率理想。

英文摘要:

      Objective To improve the analysis method of abamectin residue in leek. Methods The samples were extracted with acetonitrile, and purified by amino column. The liquid chromatography was used as a de-tection method, by using UV-detector for qualitative and quantitative analysis. Results The recovery of this pre-treatment method through recovering amino column was 98.11%~102.23%, and the relative standard deviations were from 5.31%~6.76%. The lowest detection limit was 0.01 mg/kg. Conclusion This detection method is simple, sensitive, accurate and reproducible, and can be used to detect the residues of abamectin in leek.
