SFE is used mainly for nonpolar compounds [e.g. polychlorinated biphenyls (PCBs)]. Typically, small aliquots of soil (0.5-10 g) are used for extraction. The extraction solvent is a supercritical fluid, most commonly carbon dioxide, which has properties of both a liquid and gas. The supercritical fluid easily penetrates the small pores of soil and dissolves a variety of nonpolar compounds. Supercritical carbon dioxide extracts compounds from environmental samples at elevated temperature (100-200 °C) and pressure (5000-10 000 psi). High-quality carbon dioxide is required to minimize...

Supercritical extraction is an important methodology for extracting organics from soil. As the name implies, the solvent is kept in its liquid state but above its boiling point by keeping it under pressure. Figure 12.8 shows a simplified supercritical carbon dioxide extraction setup. It is possible and common to have pumps, in addition to the one shown, to add chemical modifiers to the solvent, to increase extraction efficiency, or to extract a specific organic component [6,9-12],...

There is one case in environmental work where the methyl and methylene absorptions are useful and used. This is in the United States Environmental Protection Agency (USEPA) method for the determination of total recoverable petroleum hydrocarbons (TRPHs) in a soil or other extract. Here, a supercritical carbon dioxide extraction of a hydrocarbon-contaminated soil is made (EPA Method 3560). The extracted hydrocarbons are dissolved in... [Pg.299]

In a method for the determination of 4-nitrophenol in sewage sludge (Lee and Peart [3]) the sludge is subjected to supercritical carbon dioxide extraction and on-line acetylation. The extract is analysed by gas chromatography-mass spectrometry. Down to O.lmg kg-1 of 4-nitrophenol could be detected in sludge. [Pg.189]

Supercritical carbon dioxide extraction [98] has been applied with 85% recovery to the organophosphorus insecticides from sediments. Compounds studied include Parathron ethyl, Methiadathion and Tetrachlorovinphos. [Pg.235]
