内容記述 |
This study investigated the extraction efficiency of a couple of different extraction solvents for Certified Reference Materials of soil and sediment that include Polychlorinated Dibenzo-p-dioxins and Dibenzofurans and Coplanar Polychlorinated Biphenyls using Soxhlet and Pressurized Liquid extraction (PLE). n-Hexane, toluene, acetone, acetone/n-hexane and acetone/toluene (1:1, v/v) as solvents were examined. Unsatisfactory results for Soxhlet extraction were obtained using n-hexane alone. For PLE, satisfactory results were obtained using all solvents used for this study. The obtained results for PLE were the same or even higher than those for Soxhlet extraction. We also examined relationship between solubilityof 2, 3, 7, 8-TetraCDD/CDF in the solvent (Xdxn) and the estimated solubility (Xs). The results indicated that a linear relation was found between Xdnx and Xs for Soxhlet extraction, but no linear relation was found in those for PLE. The result suggests that choice of extraction solvent for PLE requires consideration for the analyte solubilityin extraction solvent at the temperature and pressure above boiling points of solvents. |
