摘  要：
[目的]建立同时测定蔬菜水果中克百威、3-羟基克百威、甲萘威3种氨基甲酸酯类农药残留的气相色谱-串联质谱(GC-MS/MS)法。[方法]样品经乙腈提取后,氨基柱净化,采用多反应监测(MRM)模式进行测定。[结果]3种氨基甲酸酯农药在0.005~0.25 mg/kg范围内线性关系良好(R2>0.999)。空白基质样品在0.02~0.1 mg/kg添加范围内,加标回收率为74.3%~84.3%,相对标准偏差为3.7%~15.0%,方法的检出限为0.002~0.004 mg/kg。[结论]该方法操作简单、灵敏、准确,完全可满足蔬菜水果中3种氨基甲酸酯类农药残留量的测定及确认要求。

摘  要：
[Aims] A gas chromatography tandem mass spectrometric(GC-MS/MS) method was established for determination of carbofuran, 3-hydroxycarbofuran, carbaryl in vegetables and fruits. [Methods] The samples were extracted with acetonitrile and cleaned-up by NH2 solid phase extraction(SPE) column. The analytes were detected by GC-MS/MS in multiple reaction monitoring mode(MRM). [Results] Three carbamate pesticide residues had good linear relationships within the range of 0.005-0.25 mg/kg(R2>0.999). The average recoveries ranged from 74.3 to 84.3% at the spiked level of 0.02-0.10 mg/kg, with the relative standard deviations of 3.7-15.0%. The limits of detection were 0.002-0.004 mg/kg. [Conclusions] The method is simple, high sensitivity and accurate, which can meet with the requirements for simultaneous determination and identifi cation of three carbamate pesticide residues in vegetables and fruits.
