借助气相色谱-质谱对地下水中的挥发性以及半挥发性化合物进行表征,同时采用高分辨质谱技术,在分子层面对地下水中可溶性有机物进行研究,并将其与可溶性有机物标样SRNOM中的分子组成进行了对比,发现两者在化合物类型以及化合物分布上存在明显差异。
The volatile and semi-volatile compounds in groundwater were characterized by gas chromatography-mass spectrometry, and the soluble organic compounds in groundwater were studied at the molecular level by high resolution mass spectrometry It is found that there is a significant difference between the two types of compounds and the compound distribution.
