Innovative Electrochemical Purification of Pharmaceutical Wastewater: MnCo2O4 Electrode Enabling Sustainable Energy Generation

Abstract
Microbial fuel cells are a sustainable technology that treats pharmaceutical wastewater pollutants while converting chemical energy into electrical energy through biocatalysts. This study explores an H-shaped dual-chamber microbial fuel cell (DMFC) under various organic loading conditions. The performance of manganese cobalt oxide-coated activated carbon fibre veil (MnCo2O4-CFV) electrodes was analysed, and the pollutant removal efficiency reached maximum levels under optimum conditions.Experimental results demonstrated that an organic load of 2 g COD/L achieved the highest removal efficiencies: 87% for total chemical oxygen demand (TCOD), 89% for soluble chemical oxygen demand (SCOD), and 82% for total suspended solids (TSS). At this optimal organic load, the maximum voltage, current density (CD), power density (PD), and coulombic efficiency (CE) were 942 mV, 398 mA/m², 325 mW/m², and 44%, respectively.
