SITE DOC NRMRL-CIN-1338 Gallardo*, V. University of Wisconsin - Photo Electro Catalytic Degradation and Removal of Organic and Inorganic Contaminants in Ground Waters. 2001. EPA/540/R-01/502, http://www.epa.gov/ORD/SITE. 02/22/2001 Photocatalytic oxidation offers a means of remediating low concentrations of organics in aqueous and air streams. Commercial development of this technology is limited by relatively low rates of oxidation of organics in aqueous systems and by fouling of the catalyst by other components of the waste stream. Results from this project indicate that applying an appropriate electric field across the photocatalyst extends the range of applications for this technology. Photoelectrodes that were stable during repeated use were prepared for this project by coating the photocatalyst on a metallic substrate: titanium.
