| 摘 要： | 建立了果蔬样品中氨基甲酸酯类、有机磷类、苯并咪唑类、苯甲酰脲类等各类29种农药多残留的液相色谱-串联质谱检测方法。采用QuEChERS方法进行前处理,样品经1%冰醋酸乙腈提取、醋酸钠和无水硫酸镁盐析后,上清液加入伯仲胺粉、C18粉及石墨化碳黑粉进行分散固相萃取净化。提取液经Waters SunFire C18(5μm,4.6×150 mm)色谱柱分离后,进行LC-MS/MS多反应监测模式下的定性及定量分析。29种农药的检出限在0.005~0.352μg/kg之间,定量限在0.015~1.176μg/kg之间。在1~10μg/kg的3个添加水平范围上,平均回收率在70%~119%之间,RSD小于16%。本方法可用于果蔬样品中农药多残留的确证检测。

| Abstract: | A screening method is proposed for the determination of 29 kinds of pesticide residues including carbamate,organophosphate,benzimidazole and benzoylurea in fruits and vegetables by the QuEChERS method and liquid chromatography-tandem mass spectrometry(LC-MS/MS).Pesticides interested were extracted from samples with acetonitrile containing 1% acetic acid and simultaneous liquid-liquid partitioning formed by adding anhydrous magnesium sulfate plus sodium acetate following by a simple cleanup step known by dis... |
