✦ Synopsis

Supercritical fluids are rapidly gaining importance as solvents in extraction processes. These fluids have attractive physicochemical properties that result in advantages in extraction such as ease of solvent recovery, elimination of residual solvent in the extracted medium, lower pressure drops, and enhanced mass transfer rates. In addition close to zero surface tension of these fluids enables facial penetration into the pores of a solid matrix to extract the deposited compounds. This article focuses on the use of supercritical fluids in extraction of organic contaminants from environmental matrices. Data and theoretical developments are reported on extraction of organics from water and solids, especially soils.
