Solid or liquid phase wastes containing organic contaminants which can be photodegraded are treated. The contaminants are extracted into a perfluorinated solvent which is inert to the photodegradation step. In the case of solid wastes, such as contaminated soils, sediments or sludges, the contaminant is preferably first extracted into a hydrophilic solvent, such as acetone or methanol, and/or water, and is then extracted into the perfluorinated solvent. Photo-oxidants such as ozone are preferably used in the photodegradation step. |
