Abstract
Adsorption isotherms of toluene on activated carbon were measured by time i ntegration of the breakthrough curves at 298.15 K and 308.15 K using an app aratus developed for this purpose. Isotherms were also measured at 318.15 K and 333.15 K using a microbalance. Activated carbon was used as the adsorb ent because it typically exhibits high adsorption capacities and shows pote ntial as an adsorbent to effectively remove volatile organic compounds (VOC s) such as toluene. The experimental data were correlated with the followin g adsorption isotherms: Langmuir, Freundlich, Toth, and Dubinin. All these models except the Langmuir model were able to correlate our data.
