摘要

The methods of simultaneous extraction of polycyclic aromatic hydrocarbons (PAHs) from field sediments using Soxhlet extraction and accelerated solvent extraction (ASE) were established, and the extraction efficiencies were systemically compared from procedural blank, limits of detection, spiked method recovery, and other factors. The results showed that the values obtained in this study were comparable with the values reported by other studies. In the respects of method recovery and analysis parameter there were no significant differences between ASE and Soxhlet methods for the extraction of PAHs. In this study, under the ASE operational parameters of 100 ℃, 1500 psi, and 5 minutes, and extraction solvents of acetone and hexane, it receives a reliable extraction effectiveness compared to Soxhlet extraction. Overall, considering solvent consumption and extraction time, ASE is preferable to Soxhlet extraction.
