Electrochemical Oxidation of Pollutants in Textile Wastewaters Using BDD and Ti-Based Anode Materials

Year: 2024

Type: article

Abstract: This study aims to evaluate the electrochemical oxidation of real textile wastewater using boron-doped diamond (BDD) and different titanium-based mixed metal oxide (Ti/MMO) commercial anodes, namely Ti/RuO2-TiO2, Ti/IrO2-Ta2O5, Ti/IrO2-RuO2, and Ti/RuO2/IrO2-Pt. Experiments were conducted in batch mode, with stirring, at different applied current densities. The results showed that BDD attained the best results, followed by Ti/RuO2-TiO2, which achieved total color removal, a chemical oxygen removal of 61% with some mineralization of organic compounds, and a similar specific energy consumption to BDD. The worst performance was observed for Ti/IrO2-Ta2O5, with a specific energy consumption four times superior to BDD due to a negligible organic load removal.
