Potential of Pollutant Treatment by Combined Extraction and Oxidation with Supercritical Carbon Dioxide

摘要

Compressed gases in the liquid or supercritical state can be used as solvents and reactants. This possibility can be exploited 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 possibilities and the potential of the combined process are discussed on the basis of laboratory-scale studies of both extraction and oxidation on model substances.
