摘要

采用气相色谱-质谱联用技术和高效液相色谱-紫外和/或质谱联用技术对饮用水、城市污水和工业污水处理厂出水进行了分析。在柱层析或流动注射分析绕过分析柱后,通过热喷雾界面进行电离。污染物的鉴定采用串联质谱法,通过碰撞诱导解离产生女儿离子谱。饮用水和废水处理厂流出物中的大多数污染物是人为来源的表面活性化合物或其生化降解产物。介绍和讨论了分离、检测和鉴定过程中遇到的困难,并提出了解决这些问题的技术。

Pollutants in drinking water and waste water.

Extracts of drinking water and effluents from municipal and industrial sewage treatment plants were analysed by gas chromatography-mass spectrometry and by high-performance liquid chromatography combined with ultraviolet and/or mass spectrometric detection. After column chromatography or flow-injection analysis bypassing the analytical column, ionization was performed by a thermospray interface. Identification of the pollutants was carried out by tandem mass spectrometry, generating daughter-ion spectra by collision-induced dissociation. Most pollutants in drinking water and in the effluents of waste water treatment plants are surface-active compounds of anthropogenic origin or their biochemical degradation products. Difficulties encountered during separation, detection and identification are presented and discussed and techniques for solving these problems are proposed.
