目的:建立用GC-MS能同时测定氟乙酰胺、毒鼠强、甲胺磷、甲基对硫磷、三唑酮、毒死蜱、三氯杀螨醇的测定方法。方法:样品经提取、净化、浓缩后运用气质联用仪(GC-MS)进行测定。结果:氟乙酰胺及毒鼠强的线性范围分别为5μg/ml～40μg/ml和0.5μg/ml～20.0μg/ml,五种农药的线性范围0.05μg/ml～10μg/ml,回收率为77%～112%。结论:该法快速、灵敏、准确,可用于实际检测分析。
Objective: To establish a method for simultaneous determination of fluoroacetamide, tetramine, methamidophos, parathion, triadimefon, chlorpyrifos and dicofol by GC-MS. Methods: The samples were extracted, purified, concentrated and determined by gas chromatography-mass spectrometry (GC-MS). Results: The linear ranges of fluoroacetamide and tetramine were 5μg / ml ~ 40μg / ml and 0.5μg / ml ~ 20.0μg / ml respectively. The linear ranges of the five pesticides were 0.05μg / ml ~ 10μg / ml. The recoveries were 77% ~ 112%. Conclusion: The method is fast, sensitive and accurate and can be used for the actual detection and analysis.
