摘  要:
建立蔬菜中氨基甲酸酯类农药残留的超高效液相色谱-串联质谱检测方法。样品经乙腈提取,Agilent Bond Elut QuEChERS小柱净化。质量浓度为0.025~0.80μg/mL时,4种氨基甲酸酯类农药及其代谢物线性关系良好,相关系数为0.997 4~0.999 8。在添加质量分数为0.02~0.20 mg/kg时,方法回收率为84.0%~109.9%,相对标准偏差为0.2%~12.4%,最低检测质量分数为0.003 mg/kg。该方法操作简单,准确度高,满足蔬菜中多种氨基甲酸酯类农药残留量的测定要求。

摘  要:
A method for the determination of carbamate pesticides and its metabolites residues in vegetable was developed by UPLC-MS/MS. The samples were extracted with acetonitrile, cleaned up with Agilent Bond Elut QuEChERS column. At the concentration of 0.025-0.80 μg/m L, carbamate pesticides and its metabolites had good linear relation, with the correlation coefficients of 0.997 4-0.999 8. At the spiked levels of 0.02-0.20 mg/kg, the average recoveries were 84.0%-109.9%, the relative standard deviations were 0.2%-12.4%. The method was simple, accurate.
