Abstract
The electrochemical regeneration of activated carbon has been investigated based on methods to restore the adsorption capacity of activated carbon and enhance the efficiency of pollutant removal. This study analyzes the process of decomposing pollutants on the surface of activated carbon electrochemically and restoring the adsorption capacity via regeneration. Experimental results show that electrochemical regeneration significantly extends the lifespan of activated carbon and improves the regeneration speed and efficiency considerably. This method is considered environmentally friendly and economical for regenerating activated carbon compared with conventional methods such as those involving heat, chemical reactions, and pH adjustments. Activated carbon is composed of graphene and graphene oxide at the molecular level, and the interaction of these substances with phenolic compounds is yet to be elucidated. In this study, catechol, which is a representative pollutant among phenols, is prioritized. Additionally, the adsorption and desorption between graphene and catechol are visualized via molecular-dynamics simulations and the principles of electrochemical regeneration are elucidated.
