The adsorption isotherms at the range of temperatures 298-343 K have been described by the Freundlich and Dubinin-Astakhov equations. The characteristic curves of the adsorption process have been determined. It was found out that the temperature dependence of the adsorption equilibrium was described well by the Dubinin-Astakhov model. The isosteric enthalpy of the adsorption was assigned. To describe the dependence of the adsorption isosteric enthalpy on the filling degree, the Do model and the combinations of the van’t Hoff and Dubinin-Astakhov equations in a form of the logarithmic equation were used.
