| Abstract: | A simple and effective method, the accelerated Solvent Extraction with Ethyl Acetate as Extraction coupled with high performance liquid chromatography -programed fluorescence detection （ASE-HPLC-FLD）,has been developed for the extraction and determination of 15 po｜ynuelear aromatic hydrocarbons （PAHs） in soil. The detection limits of FLD was from 0.03 μg/kg × 0.4μg/kg.The matrix spike recovery ranged from 68.1% to 110.0%. The relative standard deviations of standard addition ranged from 2% to 10% （ n= 5 ）. |
