摘要
采用顶空固相微萃取-气相色谱/质谱联用测定技术,以太湖某饮用水源地水体中甲基异莰醇-2和土臭素为主要研究对象,通过环境因子相关性分析,对异味物质的变化规律和来源作初步分析。研究结果表明,该水源地2013年的主要异味物质为甲基异莰醇-2,超标时段主要集中在夏秋高温季节(5—9月);水体中的硅藻可能是异味物质的重要产生者,底泥中的藻类和微生物次生代谢活动可能是水体产生异味的主要原因。
2-methylisoborneol and Geosmin were the main odor compounds in Taihu drinking water source,determined by headspace solid phase micro-extraction gas chromatography-mass spectrometry. On analysis of the variation and source of 2-methylisoborneol and Geosmin and the environmental factors correlated,the results showed that the main odor compound was 2-methylisoborneol in 2013,excessive time mainly occur in high temperature summer season( May to September),diatoms may be important production of odorous substances,sediment of algal and microbial secondary metabolism activities may be the main reasons for the odor of water.
