建立了环保橡胶油中多环芳烃的气相色谱／质谱（GC／MS）测定方法。样品经环已烷－二甲基亚砜两次萃取，硅胶固相萃取柱净化后，用GC／MS分离测定。优化了8种多环芳烃（PAHs）化合物的分离测定条件。结果8种PAHs回收率范围为62％－94％，日内（11=5）相对标准偏差为3．72％～6．91％。方法具有灵敏度高、准确度好、能同时分离测定8种多环芳烃化合物的优点，适合于芳烃油中多环芳烃化合物的测定。
建立瞭環保橡膠油中多環芳烴的氣相色譜／質譜（GC／MS）測定方法。樣品經環已烷－二甲基亞砜兩次萃取，硅膠固相萃取柱淨化後，用GC／MS分離測定。優化瞭8種多環芳烴（PAHs）化閤物的分離測定條件。結果8種PAHs迴收率範圍為62％－94％，日內（11=5）相對標準偏差為3．72％～6．91％。方法具有靈敏度高、準確度好、能同時分離測定8種多環芳烴化閤物的優點，適閤于芳烴油中多環芳烴化閤物的測定。

A method for the determination of polycyclic aromatic hydrocarbons （PAHs） in noncarcinogenic rubber oil by gas chromatography - mass spectrometry has been established. The samples were extracted twice with cyclohexane/dimethyl sulfoxide and then cleaned up by the cleanert silica - SPE columns. Finally , 8 PAHs in the samples were separated and quantified by the proposed method. The recoveries of the method ranged from 62% to 94% and the relative standard deviations were 3.72% -6.91%. This method is sensitive , accurate and suitable to the determination of PAHs in noncarcinogenic rubber oil.
