Abstract. Adsorption is the process of binding and removing certain substances from a solution through the use of an adsorbent. Activated carbon is the most commonly used adsorbent in the treatment of water, municipal wastewater, and organic industrial wastewaters, because of its ability to adsorb a wide variety of organic compounds, as well as the economic feasibility of use.
