摘　　要：文章建立了一种高效液相色谱-串联质谱法测定毛织物中氯菊酯防虫蛀剂含量的方法.毛织物中的氯菊酯经甲醇浸泡、超声提取、过滤后,利用液相色谱分离氯菊酯异构体,采用质谱-选择离子监测法对其作定量测定.顺、反氯菊酯的标准曲线线性相关系数均大于0.999 2,线性范围为0.01～1μg/mL.该方法对顺式氯菊酯的检出限为0.707 ng/mL、反式氯菊酯为1.645 ng/mL.在2 mg/kg、20 mg/kg的2个添加水平范围内的平均回收率在92.6％ ～ 96.9％之间,相对标准偏差（n=7）在0.2％ ～7.6％之间.与高效液相色谱法相比杂质干扰小,准确性高,检测限更低.A method has been developed for the determination of permethrin in the wool fabric by HPLC/MS/SIM. Permethrin on the wool fabric is soaked and ultrasonic extracted by methanol. After filtration, permethrin isomers were separated and qualitative and quantitative analysis was carried out by ESI/MS/MS with selected ion monitoring in the positive ion mode. The correlation coefficients of cis- and trans-permethrin were great than 0. 999 2 in the range of 0.01 - 1 μg/mL. The limits of detection （LODs）for cispermethrin was 0. 707 ng/mL and trans-permethrin 1. 645 ng/mL. The mean recoveries at the spiked level of 2,20 mg/kg were 92.6% - 96.9% , with the relative standard deviation （ n = 7 ） between 0.2% - 7.6%. The method is accurate, simple, rapid and adapts to the inspection of permethrin in wool fabric.
