Abstract: A method that accelerated solvent extraction of naphthalene and its derivatives was carried out in this research. A soil sample, mixed with some silica sand, was placed in the extract cell. Objectives were extracted by dichloromethane-acetone（V∶V,1∶1） at extraction temperature of 100 ℃ and extraction pressure of 10.342 2 MPa for 10 min. The eluent was purfied using florisil silica column after concentrated by K-D. Then naphthalene and its derivatives were analyzed by gas chromatography-mass spectrometry using a DB-5MS column. Spiked recoveries of three concentrations ranged from 64.0%~102.6% with relative standard deviation 7.6%~15.2%（n=7）.
