摘要

目的: 建立枸杞中7种有机磷农药的分析方法。方法: 采用凝胶渗透色谱(GPC)对枸杞中7种有机磷农药进行样品净化处理后

利用气相色谱-质谱联用对7种农药同时定性、定量测定。结果: 在0.05~1.00 mg ·L-1各农药组分呈现良好的线性相关

R2均>0.99

7种有机磷农药的平均回收率在79.3%~109.3%

RSD 2.39%~10.33%(n=6)

最小检测限范围为2.1~36.7 μg ·L-1。结论: 采用该凝胶渗透色谱-气质联用法同时测定枸杞中7种有机磷农药残留

准确度、精密度良好

可用于定性定量分析。

Abstract

Objective: A gel permeation chromatographic method was developed for the extraction of 7 pesticides from Chinese wolfberry. Method: Quantity and quality determination method were developed by gas chromatography with mass spectrometry. Result: In the linear range 0.05-1.00 mg ·L-1 of each pesticide

the correlation coefficient was higher than 0.99.The average recoveries were from 79.3% to 109.3% with the RSD 2.39%-10.33% (n=6).The limits of detection (LOD) for these pesticides were from 2.1-36.7 μg ·L-1. Conclusion: The method developed is reliable

accurate and can be applied for quantitative and qualitative analysis of 7 pesticides from Chinese wolfberry.
