| 摘 要： | 提出同时测定牛奶中敌百虫、甲胺磷、敌敌畏、马拉硫磷、倍硫磷五种有机磷农药残留的检测方法。在选定的色谱条件下,添加浓度在0.5～10.0μg/mL之间时5种农药的检测限分别为0.031μg/mL、0.013μg/mL、0.023μg/mL、0.019μg/mL和0.014μg/mL,回收率范围分别达81.0%～85.5%、84.5%～89.4%、79.0%～81.8%、77.3%～82.5%和77.9%～89.5%,变异系数在0.29%～3.96%之间。本方法对牛奶中有机磷农药残留的检测分析准确可靠。

| Abstract: | Five kinds（Trichlorfon,Methamidophos,Dichlorvos,Malathion and Fenthion） of organophosphate pesticide residues in milk were detected by gas chromatograph（GC）.With the selected chromatographic conditions,the lowest detection limit of five kinds of organophosphate pesticide residues were 0.031μg/mL,0.013μg/mL,0.023μg/mL,0.019μg/mL and 0.014μg/mL,respectively,within the linear concentration ranging of 0.5～10.0μm/mL.The recovery（n=3） of five kinds of organophosphate pesticide were 81.0%～85.5%,84.5%～89.4%,79.0%～81.8%,77.3%～82.5% and 77.9%～89.5%,respectively,and the relative standard deviations were 0.29%～3.96%.The method is effective and accurate for determining organophosphate pesticide residues in milk. |
