中文摘要	建立了黄瓜、番茄和豇豆中克百威和涕灭威及其代谢物3-羟基克百威、涕灭威砜、涕灭威亚砜的超高效液相色谱-串联质谱检测方法。样品经乙腈和QuEChERS(0.5 g柠檬酸二钠盐水合物、1 g无水柠檬酸钠、1 g氯化钠、4 g MgSO_4)提取盐包提取,Oasis PRiME HLB固相萃取柱通过式净化,超高效液相色谱-串联质谱(UPLC - MS/MS)进行检测,采用空白基质匹配的校准曲线外标法定量。结果显示,2种农药及其代谢物均在0.001 ~ 0.5 mg/L范围内呈良好的线性关系,相关系数均大于0.996 0。在0.02 ~ 0.2 mg/kg加标浓度范围内的平均回收率为80.4%~ 110%,相对标准偏差(RSD)为1.1%~ 4.8%。克百威、3-羟基克百威、涕灭威、涕灭威砜和涕灭威亚砜的检出限(LOD)分别为0.07、0.3、1.0、4.0、13 mug/kg,定量下限(LOQ)分别为0.2、1.0、2.0、13、42 mug/kg。
英文摘要	An ultra performance liquid chromatography - tandem mass spectrometric (UPLC - MS/MS) method was developed for the determination of carbofuran and aldicarb,as well as their metabolites carbofuran-3-hydroxy,aldicarb-sulfone and aldicarb-sulfoxide in cucumber,tomato and cowpea. The samples were extracted with acetonitrile and QuEChERS salt packets containing 0.5 g sodium sesquihydrate,1 g sodium citrate,1 g NaCl and 4 g MgSO_4,and purified by pass-through solid phase extraction using an Oasis PRiME HLB column,then analyzed by UPLC - MS/MS. The matrix effects were observed in the analysis of the analytes in sample. The quantitations were performed by the external standard method with matrix-matched calibration standards. There were linear relationships for carbofuran,carbofuran-3-hydroxy,aldicarb,aldicarb-sulfone and aldicarb-sulfoxide in the range of 0.001 - 0.5 mg/L with their correlation coefficients(r) larger than 0.996 0. Recoveries for cucumber,tomato and cowpea at spiked levels of 0.02 - 0.2 mg/kg ranged from 80.4% to 110%, with relative standard deviations(RSDs) of 1.1% - 4.8%. The limits of detection(LOD,S/N = 3) for carbofuran,carbofuran-3-hydroxy,aldicarb,aldicarb-sulfone and aldicarb-sulfoxide were 0.07, 0.3,1.0,4.0 and 13 mug/kg,respectively,and the limits of quantitation(LOQ,S/N = 10) were 0.2,1.0,2.0,13 and 42 mug/kg,respectively.
