This study presents a comparative investigation into the efficient de-colorization of Methylene Blue dye using the electro-coagulation method, employing both iron and aluminum electrodes. Electro-coagulation is a promising technique for water treatment, and the choice of electrode material can significantly influence its efficiency. Through a series of experiments, the performance of iron and aluminum electrodes in removing Methylene Blue dye from aqueous solutions was evaluated. The process parameters, including electrode material, current density, pH, and reaction time, were systematically examined to assess their impact on de-colorization efficiency. The results reveal distinct differences in the performance of iron and aluminum electrodes, shedding light on their suitability for electro-coagulation applications in water treatment.
