Compressed gases in the liquid or supercritical state can be used as solvents and reactants, for example in the dense gas extraction of pollutants from solids or liquids. The pollutants removed in this way can then be decomposed completely by total oxidation after air has been added. The potential of the combined process is discussed on the basis of laboratory‐scale studies of both extraction and oxidation.
