Activated carbon, due to its high specific surface area, has been used extensively as an adsorbate for removal of hazardous air pollutants. Most of the column adsorption studies were conducted at a specific temperature, and the major methods of data analysis include: a linear driving force approximation 1-5, an empirical method 6, and thermodynamic equilibrium 7,8. The linear driving force model considers adsorption as an irreversible reaction. As for the thermodynamic equilibrium method, an ideal adsorbed solution theory was based on the thermodynamic equivalence of each solute at equilibrium.
