摘要
目的:建立同时测定中药材柴胡中8种有机磷农药毛细管气相色谱测定方法。方法:样品前处理方法简单,样品中加入少量活性炭,可用乙腈直接提取。选用火焰光度检测器(FPD)和 DB-17毛细管柱,程序升温进行气相色谱测定。结果:8种有机磷农药(敌敌畏、甲胺磷、乙酰甲胺磷、氧乐果、久效磷、甲基对硫磷、毒死蜱、喹硫磷)的最小检出量在0.05ng～0.15ng 之间,平均回收率在82.07%～107.75%之间,RSD 在0.85%～14.00%之间。结论:该法灵敏度高、选择性强、操作简便、重现性好。
Objective： An analytical method is described for the quantitative determination of residues of 8 organo - phosphorous pesticides （ Dichlorvos, Methamidophos, Acephate, Omethoate, Ethion, M - parathion, Chlorpyrifos and quinalphos） in the Chinese Medicinal Herbs （chaihu）, Methods：The sample was extracted with acetonitrile mixed with some active carbon,and determined with GC with FPD （flame photometric detection） and DB -17 capillary column. Result：The average recoveries and RSD of the method were 82. 07% - 107.75% and 0. 9% - 14. 0% ,respectively. The limit of detection ranged from 0. 05 ng-0. 15 ng. Conclusion：The method was high sensitive, simple and rapid with good reproducibility.
