[目的]建立气相色谱法对乳油型农药制剂中多种禁止使用农药成分分析的方法。[方法]样品采用丙酮稀释,经大口径毛细管分离,气相色谱FID检测,双柱定性,内标法定量检测。[结果]6种乳油型农药中添加回收率在91.4%～105.6%之间,相对标准偏差为0.53%～3.75%。[结论]该方法可以高效、准确的对多种禁止使用农药成分同时检测。
[Objective] The research aimed to establish a method for the analysis of many kinds of banned pesticide components in EC type pesticide preparations by gas chromatography. [Method] The samples were diluted with acetone, separated by large - diameter capillary, detected by Gas Chromatography FID, double - column qualitative and internal standard. [Result] The recoveries of six kinds of emulsified oil pesticides were between 91.4% and 105.6% with the relative standard deviations of 0.53% ~ 3.75%. [Conclusion] The method can detect multiple pesticide components with high efficiency and accuracy simultaneously.
