Adsorption of carbon tetrachloride and chloroform on activated carbon at (300.15, 310.15, 320.15, and 330.15) K
The adsorption equilibria for carbon tetrachloride and chloroform vapors on activated carbon (Sorbonorit B4) were measured using a gravimetric method. The equilibrium data were obtained at (300.15, 310.15, 320.15, and 330.15) K with the pressure up to 7 kPa for carbon tetrachloride and 4.9 kPa for chloroform, respectively. The Toth and Dubinin-Astakov equations were successful in correlating the experimental isotherms. The Toth equation was used to determine thermodynamic properties such as the isosteric enthalpy of adsorption and Henry's constant. By using the Dubinin-Astakov isotherm equation, the total micropore volume of the adsorbent was determined.
