Adsorption isotherms in the approximation of Langmuir monolayer correlations

The influence of the lateral interactions and lattice monolayer cluster structure on both the adsorption kinetics and adsorption isotherms is discussed. The adsorption isotherms were theoretically calculated within the Langmuir approximation of the correlation sums at different lateral interaction energies. The adsorption isotherms were also simulated under the same conditions in a numerical experiment, based on the previously developed procedure. The applicability limits of the Langmuir correlation sum model for describing the adsorption processes were estimated from a comparison of calculated and experimental adsorption isotherms.
