Adsorption Isotherms of Benzene and Toluene on Corn Grain-Based Carbon Monolith at (303.15, 313.15, and 323.15) K

The adsorption isotherms of benzene and toluene on a newly made corn grain-based carbon monolith were measured at (303.15, 315.15, and 323.15) K using a gravimetric method. The Toth isotherm model was adopted to fit the adsorption equilibrium data of benzene and toluene. The Dubinin−Astakhov equatio...

Summary:The adsorption isotherms of benzene and toluene on a newly made corn grain-based carbon monolith were measured at (303.15, 315.15, and 323.15) K using a gravimetric method. The Toth isotherm model was adopted to fit the adsorption equilibrium data of benzene and toluene. The Dubinin−Astakhov equation was used to calculate the total micropore volume of carbon monolith. By using the Clausius−Clapeyron equation, the surface energetic character of the carbon monolith was analyzed. The thermal desorption works were carried out to investigate the interaction between the adsorbates and monolith.
