| 摘 要： | 采用高效液相色谱-二极管阵列检测器对番茄、辣椒和茄子中甲基毒死蜱残留量进行测定。样品用乙腈提取后,经Carb/NH2固相萃取小柱净化,用C8液相色谱柱、二极管阵列检测器,对甲基毒死蜱残留量的测定可取得满意的结果。该方法样品平均加标回收率为80.7%～92.4%,相对标准偏差为1.1%～4.6%;蔬菜中甲基毒死蜱检出下限为0.02mg/kg。

| Abstract: | A high performance liquid chromatography method was presented for the determination of chlorpyrifos-methyl residues in tomato,hot pepper and egg plant.The chlorpyrifos-methyl residues in the samples were extracted into acetonitrile,cleaned up using a Carb/NH2 solid phase extraction column,separated on a C8 liquid chromatography column,and detected with a diode array detector(DAD).The average spike recoveries of the method across three spike levels were between 80.7% and 92.4%(n =6),with a relative standard ... |
