中文摘要：

采用固相微萃取与气相色谱-质谱联用测定饮用水中5种常见的土霉味物质，研究了萃取温度、盐含量、萃取时间和溶液pH值等操作条件对分析方法的影响。得到的优化分析条件如下：萃取温度为65℃、盐含量为25％、萃取时间为1h；该方法的相对标准偏差〈10％，样品的加标回收率≥89％。

英文摘要：

A sensitive method of solid phase microextraction （SPME） followed by gas chromatography/mass spectrometry （GC/MS） was used for analyzing five kinds of common earthy-musty odorants. The effects of extraction temperature, salt content, extraction time, pH and other operation conditions on the analysis method were investigated. The resulting optimal conditions are 65 ~C for the extraction temperature, 25% for salt concentration and 1 h for extraction time. The relative standard deviations of the method are below 10%. The recovery rate of standard addition in the sample is over 89%.
