摘要：

建立了以顶空进样-大口径毛细柱-NPD气相色谱法测定生活饮用水、水源水、废水中吡啶含量的方法。在优化的条件下，吡啶的响应值与浓度有良好的线性关系，灵敏度高，最低检出质量浓度为0.005mg/L。该方法用于实际水样分析，结果令人满意，样品的回收率为92%-110%。该方法还具有预处理简便、不使用剧毒试剂、分析速度快、干扰少等优点。

Abstract:

A gas chromatography method with headspace-large diameter capillary column-NPD for the determination of pyridine in drinking water, source water and wastewater has been established. In the optimized situation, good linear relationship is founded between the responding counts and concentration of pyridine in water. The detection limit is 0.005 mg/L, with high sensitivity and the recovery rate of 92%-110%. The application of this method in analyzing real samples is tested and satisfied result is obtained. There are many advantages in this method, such as convenient pretreatment, without usingpoisonous reagent, quick analysis and fewinterference etc.

Key words: headspace gas chromatography, large diameter capillary column, pyridine
