| 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2 ng,定量限(LOQ)为2.5μg.g-1(定容25 mL)。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%。

| Abstract: | 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 2.5 μg·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 400 μg·g-1 to 10 000 μg·g-1.The result showed that the average recovery was from 100.1 % to 102.6 % and the RSD from 0.70 % to 2.46 %. |
