【摘要】 采用气相色谱/质谱方法(GC/MS)对产地不同的原油和重质燃料油中的多环芳烃(PAHs)进行定量分析。通过多环芳烃原始指纹谱图、多环芳烃组分分布模式和特征比值的比较对上述原油和重质燃料油进行鉴别。基于多环芳烃诊断比值的主成分分析得到了两个主成分,分别解释总变量的64.4%和30.7%。结果表明所选诊断比值可以用来鉴别原油和重质燃料油,为溢油鉴别提供技术支撑。更多还原

【Abstract】 Polycyclic aromatic hydrocarbons(PAHs) in four crude oils and four heavy fuel oils(HFOs) produced in different countries were analyzed quantitatively using gas chromatography/mass spectrometry(GC/MS).Total ion chromatograms(TIC) ofPAHs,distribution of PAHs and diagnostic ratios of PAHs were employed to distinguish the differences among the four crude oils and HFOs.Two factors,which accounted for respectively 64.4%and 30.7%of the total variations of the indices,were obtained by principal component analysis.The results indicated that the indices selected in this study were suitable for distinguishing the differences of various crude oils and HFOs,and can be used to determine the sources of marine oil spills.更多还原
