Enhanced Cr(VI) removal and power generation in Tannery Wastewater Using ORR-Optimized Cathodes in single-chamber microbial fuel cells

Key Points

• The study aims to improve the removal of hexavalent chromium and increase power generation in microbial fuel cells.
• Utilized single-chamber microbial fuel cell design
• Optimized cathodes for oxygen reduction reactions
• Tested effectiveness with tannery wastewater
• Measured both Cr(VI) removal rates and power output
• Significant enhancement in Cr(VI) removal compared to standard configurations
• Increased power generation alongside improved metal removal
• Optimized cathodes showed better performance in both metrics
