Study on Adsorption Isotherm of Toluene and Acetone onto Activated Carbon C40/4

In order to study the law of the adsorption isotherm of organic vapour on activated carbon C40/4, the adsorption isotherms of toluene and acetone on activated carbon (C40/4) were measured by time integration of the breakthrough curves at 288.15 K, 293.15 K and 298.15 K using an apparatus developed for this purpose. The relationship between these parameters of the adsorption isotherm and the temperature, which is based on the theory of langmuir from the aspect of a dynamic equilibrium, was theoretically analyzed. The experienced adsorption isotherm model, which describes the adsorption isotherm of organic vapour on activated carbon C40/4 at different temperature, was proposed. The experimental data were correlated with the Langmuir adsorption isotherms, which is a fundamental theoretical relation for temperature. An excellent agreement between experimental data and computing data of these equations, whose tolerance is less than 6%, is observed. The mathematical model method offers effective solution for the capacity of organic vapour on activated carbon to forecast and optimize the adsorption process.
