| 摘 要： | 采用顶空固-相微萃取（HS-SPME）和气相色谱-质谱联用仪（GC/MS）检测技术对垃圾渗滤液中挥发性和半挥发性物质进行了分析,所运用的SPME萃取纤维是非键合聚二甲基硅氧烷（以下简称PDMS）,涂层厚度分别为100μm（主要适合挥发性）和7μm（主要适合半挥发性）,在室温下搅拌（1 200 r/min）5 min后,顶空萃取60 min后,迅速在GC-MS进样口250℃解析5 min后进行分析检测.检出挥发性有机物有8种,其中主要类别是酮类、酚类和醇类等3种.

| Abstract: | A method of headspace solid-phase microextraction （HS-SPME） coupled to gas chromatography/mass spectrometry （GC/MS） for detection volatile and semi-volatile constituents in landfill leachate was developed. Results was obtained under the conditions of mixing （1 200 r/min） at room temperature for 5 minutes, headspace extraction 60 minutes with two fibers of 100 μm and 7 μm non-bonding polydimethylsiloxane （PDMS）. 8 kinds of volatile components are detected, mainly ketones, phenols and alcohols. |
