APPLICATION OF MICROWAVE ASSISTED EXTRACTION TO THE ANALYSIS OF DIOXINS FROM SOIL AND SEDIMENT CERTIFIED REFERENCE MATERIALS
Microwave assisted extraction (MAE) was applied to the extraction of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (DL-PCBs) from soil and sediment certified reference materials.Six grams of the samples were extracted with mixed solvents composed of 6 ml of toluene, 2.4 ml of water, and 4.8 ml of ethanol at a temperature of 125℃ for 30 min. The average concentrations of PCDD/DFs and DL-PCBs corresponded to the results of the certified value, and the reproducibility of this MAE method was below 19％ of the relative standard deviation for the certified reference materials. These results indicated that a rapid analysis of dioxins from soil and sediment could be performed with accuracy and precision by our MAE method.
