Determination of Acenaphthene,Fluorene and Dibenzofuran Content in Washing Oil by Gas Chromatography

A gas chromatography method for the determination of acenaphthene,fluorene and dibenzofuran content in the washing oil was established.The method used ethanol as solvent;the sample was separated by HP-5 capillary pillar gas chromatography,and determined by FID detector;quantitative determination was carried out by the external standard method.The results show that the composition in the washing oil can be well separated;the method has good accuracy and precision.
