吹扫捕集/气相色谱-质谱法测定土壤中的苯系物

Determination of benzene in soil by purge and trap/gas chromatography-mass spectrometry

工业发展工程中会使用大量的苯系物。苯系物对人体有着严重的危害,在工业生产中如果将苯系物排放到周围的环境中将会导致严重的土壤污染。土壤中的苯系物主要有苯、甲苯、乙苯、异丙苯、二甲苯。本文主要使用吹扫捕集/气相色谱-质谱法对上述土壤中的苯系物进行测定。

With the development of social economy,industry is also developing continuously,and a large amount of benzene series will be used in industrial development projects.Benzene is a serious hazard to humans.In industrial production,if benzene is discharged into the surrounding environment,it will cause serious soil pollution.The main benzenes in the soil are benzene,toluene,ethylbenzene,cumene and xylene.In this paper,the benzene series in the above soil was mainly determined by purge and trap/gas chromatography-mass spectrometry.
