摘  要:
建立了甘蓝(Brassica oleracea L.)和土壤中虱螨脲残留的超高效液相色谱-三重四极杆串联质谱(UPLC-MS-MS)快速检测的方法。样品用酸化乙腈提取,以Qu ECh ERS法净化,超高效液相色谱-串联质谱电喷雾负离子模式检测。结果表明,虱螨脲在5~500μg/L范围内,浓度和响应峰面积线性关系良好。在0.01、0.02、0.1和0.5 mg/kg 4个添加浓度下,平均回收率在78.5%~113.6%,相对标准偏差(RSD)为2.5%~8.5%(n=6),虱螨脲在甘蓝和土壤中的定量限(LQD)均为0.01 mg/kg。该方法适用于甘蓝和土壤中虱螨脲的检测。

摘  要:
An ultra performance liquid chromatography-tandem mass spectrometry(UPLC-MS-MS) method was developed to determine residue of lufenuron in cabbage and soil. Samples were extracted with acidified acetonitrile, purified by Qu ECh ERS method and determined with UPLC-MS-MS.The results showed that the linear ranges were 5 ~500 μg / L and the correlation coefficients were higher than 0.998. The average recoveries were 78.5% ~113.6% when the spiked levels were 0.01 、0.02、0.1and 0.5mg / kg, the relative standard deviations were between 2.5% and 8.5%(n=6).The limits of quantity were both 0.01 mg /kg in cabbage and soil. The method applies to determine lufenuron in cabbage and soil.
