Photocatalytic Oxidation and Reduction Chemistry and a New Process for Treatment of Pink Water and Related Contaminated Water
Abstract
This project was carried out at the National Renewable Energy Laboratory (NREL), Sandia National Laboratory (SNL), and by a group at the University of Idaho (UI) working under subcontract to NREL. The initial focus was on photocatalytic oxidation and reduction chemistry that could use sunlight as the photon source. This work demonstrated the technical feasibility of the photocatalytic processes; however, the process removed the hazardous components of pink water at such low efficiency that it would be expensive to operate lamps in a treatment system. Technical success in removing trinitrotoluene (TNT) from water by photocatalytic reduction chemistry led us to test that as a pretreatment step for a biological treatment process. The photocatalytic reduction of TNT did render the simulated pink water more amenable to mineralization by Phanerochaete chrysosporium. This result led us to explore other chemistry for removal of TNT and related explosives from water.
