摘要：
采用固相萃取净化，气相色谱电子捕获检测器检测，建立了金银花中9 种拟除虫菊酯农药残留量的检测方法。金银花样品经正己烷涡旋振荡提取、TPH固相萃取柱净化后，用气相色谱检测。9 种拟除虫菊酯农药的线性范围在0.01～0.8 mg/L，平均回收率为82.8%～104.6%，相对标准偏差为3.5%～5.7%，检出限为0.002～0.005 mg/L。该方法灵敏、准确，适用于金银花中9 种拟除虫菊酯类农药残留量分析。

Abstract:
A method was developed for the determination of 9 pyrethroid pesticide residues in honeysuckle with solidphase extraction and gas chromatography. The results showed that average recoveries of 9 pesticides spiked at 0.02, 0.1 and 0.5 μg/g were in the range of 82.8%–104.6% with relative standard deviation (RSD) of 3.5%–5.7%. The linear range of the presented method was 0.01–0.8 mg/L, and the limits of detection (LOD) were 0.002–0.005 mg/L. The method is sensitive and suitable for the analysis of pyrethroid pesticide residues in honeysuckle.
Key words: gas chromatography, solid-phase extraction, pyrethroid, pesticide residue, honeysuckle
