摘　　要：以石油醚为溶剂，索氏提取法提取纺织品中的氯菊酯。采用反相高效液相色谱法，使用PDA检测器，Hypersil BDS C18色谱柱，流动相V（乙腈）：V（水）=88：12，对纺织品样品中氯菊酯含量进行了测定。该方法的检出限（LOD）为2ng，定量限（LOQ）为2．5μg·g^-1（定容25mL）。氯菊酯工作曲线方程为Y=3855．8＋2697312．4X，相关系数r=0．9999。添加水平400～10000μg·g^-1，平均回收率100．1％～102．6％，相对标准偏差0．70％～2．46％。Permethrin was extracted with petroleum ether by soxhlet extraction apparatus from the fabric samples, and it was determined by a high performance liquid chromatography with photodiode-array detector, Hypersil BDS C18 chromatographic column, and the mobile phase was V（acetonitrile） ： V（redistilled water） = 88 ：12, respectively. The content of permethrin was determined under these operation conditions. The LOD was 2 ng and LOQ was 2.5μg ·g ^-1 （constant volume 25 mL）, respectively. The linear equation of permethrin was Y = 3 855.8 ＋2 697 312.4X, and the correlation coefficient was 0. 999 9. The fortification level was from 400μg ·g ^-1 to 10 000 μg ·g ^-1The result showed that the average recovery was from 100 .1% to 102.6% and the RSD from 0.70% to 2.46 0%.
