| 目的 建立气相色谱-串联质谱法(gas chromatography-mass spectrometry, GC-MS)测定韭菜中拟除虫菊酯类农药残留的分析方法。方法 样品采用QuEChERS处理, 经乙腈提取, 氯化钠盐析后, 采用N-丙基乙二胺(primary secondary amine, PSA)净化, 浓缩定容后用GC-MS在选择离子监测模式(select ion monitoring, SIM)下进行测定, 外标法定量。结果 7种拟除虫菊酯农药在质量浓度0.01~1.0 μg/mL范围内, 线性关系良好, 相关系数(r2)在0.9989~0.9995之间; 检出限为0.6~3.0 μg/kg。分别向韭菜样品中加入标准品0.01、0.1、0.5 mg/kg时, 加标平均回收率为85.4%~102.4%, 相对标准偏差(n=6)为1.8%~6.1%。结论 该方法简便快速、灵敏度好、准确度高, 可用于韭菜样品中拟除虫菊酯类农药残留的测定。 |

| Objective To establish an analytical method for the determination of pyrethroid pesticide residues in Chinese chives by gas chromatography-mass spectrometry (GC-MS). Methods The samples were treated by QuEChERS method, extracted by acetonitrile, salted out with sodium chloride, purified with N-propyl secondary amine (PSA), and after concentrated and stabilized, the samples were determined by GC-MS under select ion monitoring (SIM), and external standard method was used for quantification. Results The linear relationship of 7 pyrethroids was good in the mass concentration range of 0.01?1.0 g/mL, and the correlation coefficient (r2) were 0.9989?0.9995. The limits of detection were 0.6?3.0 g/kg. When adding standard 0.01, 0.1, 0.5 mg/kg to leek samples, the average recoveries were 85.4%?102.4%, and the relative standard deviations (n=6) were 1.8%?6.1%. Conclusion This method has the advantages of simplicity, rapidity, good sensitivity, and high accuracy, and can be used for the determination of pyrethroid pesticide residues in leek samples. |
