ABSTRACT:
The object of the present invention is a method for the photocatalytic treatment of aqueous mixtures of polluting substances. Such a method consists in submitting such mixtures to irradiation in the presence of titanium dioxide while they are circulating inside a reactor formed by a hollow space of not more than 5 cm of thickness, whose inner wall is the wall of a lamp emitting at least a fraction of its radiations with a wavelength shorter than 400 nm.
In this reactor a cooling sheath is not provided between the lamp and the reaction mixture and temperature control is accomplished by means of the circulation of the same reaction mixture inside the reactor.
