Activated carbon adsorption theory

Activated carbon adsorption theory explains how activated carbon captures contaminants through a surface process. The carbon's porous structure provides a large surface area, allowing pollutants like chemicals or odors to adhere to it. When contaminated air or liquid passes through the activated carbon, molecules of pollutants are attracted and stick to the surface due to physical forces (adsorption). This process effectively removes unwanted substances from the environment, making activated carbon an efficient filter for cleaning air, water, and other fluids. The capacity to adsorb depends on the pore structure and surface area of the activated carbon.
