Title: Photoelectrochemical discoloration and degradation of organic pollutants in aqueous solutions.
Author: Bertazzoli, R

Abstract: PHOTOELECTROCHEMICAL DISCOLORATION AND DEGRADATION OF ORGANIC POLLUTANTS IN AQUEOUS SOLUTIONS. Organic compounds responsible for the color of wastewaters are usually refractory to biological digestion. In this paper the photo-assisted electrolysis process is used for color removal from three of the most colored wastewaters, which are daily generated in large amounts: the E I bleach Kraft mill effluent, a textile reactive dye effluent and a landfill leachate. Electrolysis was carried out at 26,5 mA cm(-2) in a flow reactor in which the anode surface was illuminated by a 400 W high pressure Hg bulb, In all experiments 70-75% of color reduction was observed which was also followed by a net organic load oxidation.
