Industrial waste water which was highly loaded by halogenide phenols was photooxidized by laboratory-scale photooxidation of these organic impurities in the presence of aerotropic and titaniumdioxide as photocatalyst.
The disappearance of organic compounds was determined as a function of the irradiation time. Some contaminants such as 2-chlorophenol, 2-bromophenol, 3-bromophenol, 4-bromophenol, 2,4-dibromophenol and 2,6-dibromophenol were photodegraded separately to obtain information on the reaction rates, reactivities, and reaction mechanisms of the photooxidation, and on the stoichiometric correlation between organic reactant and inorganic products concentration in the course of the photocatalytic photoreaction.
