Abstract
The current study uses the sol-gel approach to synthesize a new Dimensionally Stable Anode (DSA) covered with nanoparticles. The objective is to enhance the electrocatalytic activity and overall performance of the anodes in treating synthetic industrial wastewater containing reactive dyes. CuO and TiO2 nanoparticles are coated using a thermal decomposition technique on a titanium electrode. The DSA surface gains more surface area and better catalytic capabilities when nanoparticles are coated on it. By optimizing the electrochemical processes involved in effluent treatment, this novel approach seeks to improve the effectiveness and environmental friendliness of wastewater remediation in industrial settings. The nanomaterials coated DSA shows a notable improvement in the removal of reactive dye (methylene blue) from aqueous solutions. Absorbance was measured for untreated and treated samples withdrawn at periodic intervals of time at λmax 665 nm for methylene blue dye using UV-spectrophotometer. These absorbances were further used to estimate percentage color reduction which is 94 % after 105 minutes of electro-treatment. This innovative approach offers enhanced catalytic activity and stability, making it well-suited for efficient electrochemical treatment of diverse industrial effluents. By using cutting-edge oxidation methods, the coating’s incorporation of nanoparticles not only enhances the DSA’s overall performance but also helps remove impurities. Through the provision of a sustainable and affordable wastewater remediation solution, the technology investigated in this work has the potential to completely transform industrial effluent treatment processes, encouraging environmental stewardship and guaranteeing regulatory compliance.
