ABSTRACT:
An improved method for detoxifying waste materials contaminated with halogenated aromatic hydrocarbons is disclosed. The method provides for detoxification of halogenated aromatic compounds by electrophilic aromatic substitution. The method also provides for the dehalogenation of the lower congeners of such halogenated aromatic compounds, as a result of chemical activation via electrophilic aromatic substitution, followed by nucleophilic aromatic dehalogenation. In addition, the method provides for the more complete dehalogenation of mixtures of halogenated aromatic compounds that contain both higher and lower congeners by increasing the efficiency of dehalogenation of the lower congeners.
