(583i) Degradation of Organic –Contaminants from Wastewater By Photocatalytic-Methods Via TiO2 Thin Films and Simultaneous Production of Hydrogen-Preliminary Results
The new focus on the Energy-Water Nexus is the ability to generate energy from wastewater treatment. In particular, contamination from agriculture extensive use of herbicides and pesticides lead to an important contamination of water supply. A four- step technology is being developed to recycle contaminated water and produce hydrogen as potential use in fuel cells. The technology is based on the use of TiO2 thin films to replace the current costly use of nanoparticles in batch-designed systems that requires elimination of the particles by filtration. The four steps involved in the technology include a- Manufacturing and characterization of the thin films, b-Testing the production of Hydrogen and comparison with other techniques, C-Testing the elimination of agricultural-based contaminants (such as herbicides) and d-Testing the combination of step b and c to simultaneously produce hydrogen and decontaminate water. The production of H2 via the thin films has been achieve based on pure water.Â This work is focuses on the use of advanced oxidation techniques, specifically the use of photo-catalytic processes viaÂ TiO2 nanoparticlesÂ to degrade herbicides, such asâ¦.Â (part C). The reactor equipped with UV-lamp and the use the TiO2 nanoparticles , has been applied to the degradation of contaminants via UV-photocatalytic methods. This research is centered on the reduction kinetics of the pollutants by using UV-photocatalytic processes suitable for the potential simultaneous production of H2 (g) from wastewater. This will be the next effort in the investigation.
