Electrochemical Degradation of Remazol Black B Using Carbon Electrode

Abstrak

The presence of dye-containing wastewater in the environment poses significant risks to both ecosystems and human health. This study aimed to investigate the utilization of carbon electrodes derived from battery waste for the electrochemical degradation of Remazol Black B (RBB), determine the effect voltage, electrolysis time, and evaluate the degradation performance. Electrochemical degradation experiments were conducted using recycled carbon electrodes obtained from battery waste, while the effects of voltage and electrolysis time on decolorization efficiency were monitored using a UV–Vis spectrophotometer. The results showed that the optimum degradation conditions were achieved at voltage of 15 V and an electrolysis time of 20 min, resulting in 100% decolorization efficiency. At lower voltages, decolorization efficiencies of 70% and 100% were obtained at 5 V for 60 min and 10 V for 30 min, respectively. These findings demonstrate that carbon electrodes from battery waste can serve as an effective and sustainable alternative electrode material for dye wastewater treatment, offering comparable performance while promoting the valorization of waste materials.
