| 摘 要： | 研究了草莓中的9种有机磷农药(包括甲胺磷、乙酰甲胺磷、治螟磷、氧乐果、马拉硫磷、杀螟硫磷、对硫磷、丙溴磷、三唑磷)残留量的气相色谱测定方法。采用乙腈提取,DB-1701P柱色谱分离,FPD检测器检测,9种有机磷农药在17 min内获得良好的分离,线性相关系数r2为0.992 51~0.999 92,检测限可达0.01~0.04 mg/kg,当添加水平为0.4 mg/kg时,回收率范围为83.2%~102.8%。该法快速灵敏,且易操作。

| Abstract: | A method for determination of 9 organophosphorus pesticides residue （ including methamidophos, acephate, sulfotep, omethoate, malathion, fenitrothion,parathion,profenofos and triazophos）in strawberry by gas chromatography was investigated.The nine pesticides could be well separated within 17 min in a DB-1701P column after extacting with acetonitrile.The pesticides were detected with FPD detector.As a spiked level was 0.4 mg/kg, the recovery of the method for the pesticides were 83.2%-102.8%, the correlation coefficient ranged from 0.992 51 to 0.999 92, the detection limits were 0.01-0.04 mg/kg.The method is quick, sensitive and easy in operation. |
