The photocatalytic oxidation of low concentration, aqueous solutions of dichloroacetic acid (DCA) - a typical by product of chlorine disinfection - was studied employing titanium dioxide and UV radiation. The study aims at the development of an intrinsic reaction kinetics to be apt for scaling-up purposes. This objective  can be achieved only if the laboratory reactor is precisely modeled in order to use the complete mathematical description of de process in combination with a parameter estimation to evaluate the reaction kinetic constants.
