| Abstract: | Objective ] The research aimed to obtain accurate and rapid determination of polycyclic aromatic hydrocarbons （PAHs） in soil. Method ] Using acetonitrile as the solvent, 16 polycyclic aromatic hydrocarbons were extracted by accelerated solvent extraction （ASE）. The ex- tract was dehydrated and concentrated, and were purified by the Florisil solid phase extraction. Result] The detection limits were 0.41 -3.97 Ixg/kg. The recoveries of the spiked sample （0.5 - 20.0 mg/L） were 81.3% - 121.0%, with relative standard deviations were 1.5% - 8.8%. Conclusion ] The method effectively removed impurities, and reduced extremely the preprocessor time. It was concluded that the method had high recovery, high sensitivity and good reproducibility. The developed analytical method had been applied successfully to the determination of PAHs in soil. |
