Ruthenium-based electrodes for electrooxidation of organic pollutants from industrial wastewater

Popis výsledku v původním jazyce

Industrial wastewater generated from painting and coating processes often contains complex mixtures of organic solvents with high chemical oxygen demand. This makes them difficult to treat with conventional biological methods. Among the promising technologies for the degradation of such pollutants is electrochemical oxidation, one of the advanced oxidation processes. These processes are recognized for their ability to generate highly reactive oxidizing species and are effective and sustainable solutions for wastewater treatment. This study investigates the electro-oxidation of such wastewater using a titanium electrode coated with ruthenium oxide, a material known for its high electrical conductivity, chemical stability, and catalytic activity for oxidation reactions. The ruthenium oxide layer was applied using magnetron sputtering, followed by thermal oxidation in an oxygen-rich atmosphere. The Ru based electrode represents a cost-effective alternative to other active dimensionally stable type anodes, such as those based on iridium or platinum. The objective of this work is to evaluate the effectiveness of the ruthenium oxide coated electrode in reducing the chemical oxygen demand of industrial wastewater. The study focuses on how key process parameters, including current density, pH, and chloride ion concentration (added to promote the formation of oxidative chlorine species), influence the overall treatment efficiency.
