Photooxidation of the antidepressant drug Fluoxetine (Prozac®) in aqueous media by hybrid catalytic/ozonation processes.

This article examines the oxidative disposal of Prozac(®) (also known as Fluoxetine, FXT) through several oxidative processes with and without UV irradiation: for example, TiO(2) alone, O(3) alone, and the hybrid methods comprised of O(3) + H(2)O(2) (PEROXONE process), TiO(2) + O(3) and TiO(2) + O(3) + H(2)O(2) at the laboratory scale. Results show a strong pH dependence of the adsorption of FXT on TiO(2) and the crucial role of adsorption in the whole degradation process. Photolysis of FXT is remarkable only under alkaline pH.
