摘要
介绍了可测定水中挥发性有机物(VOCs)的吹扫捕集−气相色谱法与吹扫捕集−气相色谱/质谱法,分析了它们的优缺点,对方法的检出限、精密度、准确度等进行了比较。吹扫捕集−气相色谱法应用较为广泛,但无法实现多种挥发性有机物的同时测定。吹扫捕集−气相色谱/质谱法可大大缩短实验时间,减轻实验人员的工作量,实现多种挥发性有机物的同时测定。另外介绍了水中挥发性有机物在线监测技术的研究进展。
The gas chromatography(GC)and gas chromatography/mass spectrometry(GC/MS)coupled with purge and trap(P&T)apparatus for the determination of volatile organic compounds(VOCs)in water were introduced.The advantages and disadvantages of both techniques were analyzed,and their detection limits,precision,and accuracy were compared.The P&T-GC is widely used,but not available for simultaneous determination of multiple VOCs.The P&T-GC/MS greatly shortens the experimental time,reduces the workload of the experimental staff,and achieves the simultaneous determination of multiple VOCs.The research progress in online monitoring of VOCs in water was summarized。
