摘要
本文介绍了在同一提取、检测条件下,对番茄、茄子中乙草胺、赛克津、除草通和丁草胺残留量的分析方法。检测样品用丙酮:石油醚(1∶1V/V)提取后,经4％硫酸钠水溶液液——液分配定容后,用气相色谱带电子捕获检测器(5％OV—101为固定液的填充柱)测定该四种农药的残留量。番茄的方法回收率为81.60～101.64％;茄子为82.03～99.72％;仪器的最低检出量限:乙草胺为1.02×10^(-11)克、赛克津为1.70×10^(-11)克、除草通为1×10^(-11)克,丁草胺为40×10^(-11)克,样品的最小检出浓度为0.001～0.01毫克/千克。
The residual analysis of acetochlor, metribuzin, phendimethalin and butachlor in tomatoes and eggplants are reported. The samples extracted with acetone: petroleum benzine (1:1; v/v)were detected by GC-ECD. The fortified recoveries of the pesticides were 81.60-104.64％ for tomatoes and 82.03-99.72％ for eggplants, respectively.
