| 摘 要： | 对神术原煤分别用苯及石油醚作萃取溶剂进行索式萃取，采用硅胶柱层析纯化，利用气相色谱/质谱联用仪（GC／MS）分别对上述萃取液的硅胶层析产物进行了解折，并对其中的9种多环芳烃（PAHs）进行了定量测定；研究了不同萃取剂所得萃取液中多环芳烃的分布。结果表明，神木原煤中的PAHs以两环、三环和四环PAHs为主，苯萃取液与石油醚苹取液中PAHs的分布大体相同，但在丰度上有很大差别。

| Abstract: | After samples were extracted by the Soxhlet extractor with benzene and petroleum ether,and then simple purified by silica gel column,the 9 US EPA specified polycyclic aromatic hydrocarbons(PAHs) in Shenmu raw coal were quantitatively analyzed with a gas chromatograph/mass spectrometer(GC/MS).The distribution characteristics of 9 PAHs in benzene and petroleum ether extractions were also investigated.Experimental results show that there are mainly 2-to 4-ringed PAHs in 2 extractions.While the abundances of PA... |
