地下水中痕量有机污染物的气相色谱──质谱分析

Study on the Analysis of Trace Organic Pollutants in the Underground Water by Gas Chromatography and Mass Spectrometry

采用ＧＣ和ＧＣ／ＭＳ法对炼油厂周围地下水中的痕量有机污染物进行了分析和鉴定。应用ＧＤＸ—１０２直接吸附有机物，所得浓缩样品除去残留水分后，用二氯甲烷将收集物洗脱到浓缩瓶中，然后进行水质痕量有机物定性定量。根据已有的数据，对炼油厂周围的地下水进行评价。

Trace organic pollutants in the underground around the oil refining works are analyzed and identified by gas chromatography and mass spectrometry. GDX-102 was used to absorb the organic compounds directly. After the moisture is driven off, the trapped organic compounds are eluted into K-D concentrate bottles with dichboromethane. The concentrated samples are analyzed by gas chromatography and mass spectrometry. Based on the results, the quality of the underground water around the oil refining works was also assessmented.
