摘要
建立了一种新的水环境样品预处理方法。将水相中目标污染物萃取至毛细管固定相中 ,经微量有机溶剂解吸 ,直接在高效液相色谱上进样分析。该方法对蒽、荧蒽和 1 ,2 苯并蒽 3种多环芳烃的检测限分别为0 .9μg L ,0 .7μg L和 0 .1 μg L。相对标准偏差 5 .1 %～ 6.3 % (n =7)。
Capillary solid-phase microextraction, a sample preparation technique, was established and applied to the, determination of polycyclic aromatic hydrocarbons in, water by coupling to high-performance liquid chromatography (HPLC) The analytes were extracted onto the polymer film of a piece of gas chromatographic capillary and desorpted into HPLC injector by a small amount of organic solvent. The limits of detection for anthracene, fluoranthene and 1, 2-benzanthracene were 0.9 mug/L, 0.7 mug/L and 0.1 mug/L respectively. Good reproducibility was obtained with RSD ranging from 5.1% to 6.3% for 10 mug/L spiked samples (n=7).
