建立了吹扫捕集气质联用法测定水中吡啶的方法,优化了吹扫条件,用自动进标样的方法绘制工作曲线,方法的检出限为0.08μg/L,相对标准偏差在1.5%～5.1%之间,方法用于地表水、生活污水和化工废水中吡啶的测定,进行了加标回收实验,回收率在82.5%～102.5%之间。 A method for the determination of pyridine in water by purge and trap mass spectrometry (GC-MS) was established. The purge conditions were optimized and the working curve was drawn by automatic injection of standard sample. The detection limit was 0.08 μg / L and the relative standard deviation was 1.5% 5.1%. The method was applied to the determination of pyridine in surface water, domestic sewage and chemical wastewater. The spiked recovery experiments were carried out. The recoveries ranged from 82.5% to 102.5%.
