| Summary: | 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/RuO<sub>2</sub>-TiO<sub>2</sub>, Ti/IrO<sub>2</sub>-Ta<sub>2</sub>O<sub>5</sub>, Ti/IrO<sub>2</sub>-RuO<sub>2</sub>, and Ti/RuO<sub>2</sub>/IrO<sub>2</sub>-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/RuO<sub>2</sub>-TiO<sub>2</sub>, 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/IrO<sub>2</sub>-Ta<sub>2</sub>O<sub>5</sub>, with a specific energy consumption four times superior to BDD due to a negligible organic load removal. |
