摘要
采用固相萃取及气质联用(SPE—GC—MS)的方法对我国北方某市自来水中多环芳烃(PAHs)的污染水平及其在传统自来水处理过程中的行为进行了研究。结果表明:①从原水中检测出了9种PAHs,其总浓度为64～208ng/L,并有季节性变化趋势;②从管网水中也检测出了9种PAHs,总浓度为87～198ng/L;③常规处理工艺能去除26.8%～62.7%的PAHs,但是在管道输送过程中发现存在二次污染。
Solid phase extraction (SPE) and gas chromatograph-mass spectrometer (GC-MS) were used to investigate the pollution load of polycyclic aromatic hydrocarbons (PAHs) on drinking water in a southern city and their behavior in the traditional drinking water treatment. The result shows that nine kinds of PAHs are detected from raw water, and their total concentration is 64-208 ng/L accompanied by a tendency of seasonal change. Nine kinds of PAHs are detected from tap water with total concentration of 87-198 ng/L. The conventional treatment process can remove PAHs in a rate of 26.8%- 62.7%, but secondary pollution is observed during pipe transfer of water.
