摘　　要：采用超临界流体色谱法，测定柴油中单环和多环芳烃的含量。芳烃加标回收实验测定结果的回收率在97.5%-101.6%之间。单环和多环芳烃的重复性实验的测定结果最大偏差不超过0.4个单位。与质谱法分析的数据对比，两种方法的线性相关系数可达到0.99以上。Supercritical fluid chromatography was used to determine mono-aromatic and polycyclic aromatic hydrocarbons （PAHs） content of diesel. The experiment of aromatic standard recovery rate showedthat the recovery rate result wasbetween 97.5%-101.6%. The maximum deviation of repeatability experiment for mono-aromatic and polycyclic aromatic hydrocarbons （PAHs） was notmore than 0.4 units. Compared with the method of mass spectrometry, the linear correlation coefficient of the two methods could reach above 0.99.
