环境样品中复杂有机污染物的定量分析方法

Quantitative Analysis of Complex Organic Contaminants in Environmental Sample

利用吹扫捕集-气质联机,建立了以污染场地的污染物质为标准物质、对地下水中挥发性芳烃进行定量分析的新方法。该方法标准物质容易获得,定量数据可靠,定量信息全面,地下水中挥发性芳烃的方法检出限达0.22μg/L,且用色谱峰面积百分比对地下水中苯系物(BTEX)定量与用BTEX标准物质定量结果比较,相对标准偏差RSD<5%。

Using the specific contaminants from contaminated site as the standards substance to set up a method of quantitative analysis of Volatile Arene in groundwater by purge ＆ trap gas chromatography-mass spectrometry （P ＆ T- GCMS）. The standard material of the method is easy to obtain, and the data is credible and quantitative information is comprehensive, the method detection limit （MDL） of Volatile Arene reaches to 0.22 μg/L. The BTEX in groundwater and in standard substance is determined quantitatively by percentage of peak area respectively, the RSD is less than 5%.
