| 摘 要： | 建立了韭菜中16种农药的多残留分析方法。韭菜样本经微波炉加热处理,乙腈提取,新型固相萃取柱Cleanert TPT净化,以气相色谱-质谱-选择离子监测模式测定。结果表明:微波处理、固相萃取净化可以有效去除基质干扰,16种农药在0.02~2 mg/L范围内线性关系良好;在0.01和0.5 mg/kg两个添加水平下的平均回收率分别在84.6%~124.2%和92.4%~98.5%之间,相对标准偏差 (RSD) 均小于20%;16种农药的检出限(LOD)在1~6 μ g/kg范围内。

| Abstract: | A rapid and effective method was developed for the determination of sixteen pesticides in leek.Leek samples were heated by microwave,extracted by acetonitrile,cleaned up with Cleanert TPT SPE column and detected by GC-MS under SIM mode.The results showed that it was effective to remove the interferences with the microwave treatment and SPE cleanup.The linearity of sixteen pesticides was satisfied between 0.02 and 2 mg/L.The average recoveries fortified at 0.01 and 0.5 mg/kg were 85%-124% and 92%-98%,respect... |
