In this manuscript, the isotherm of the adsorption of toluene molecules in the Cs+ cationic form of the MFI-type synthetic zeolite 5-modification at a temperature of 303 K and the adsorption mechanism obtained in the experiment in the relative pressure coordinate are presented. The adsorption isotherm was measured using a universal high-vacuum device. Differential values of Gibbs free energy were calculated from thermodynamic equilibrium values. Based on the values of free energy, the adsorption isotherm was recharacterized by the three-state equation of micropore saturation theory. It was demonstrated that the values obtained in the experiment and the theoretically estimated values agree, and that the amount of cations in the zeolite is correlated with the coefficient of adsorption in the first term of the theory of volumetric filling of micropores equation. At a relative pressure value of P/Ps=0.06, it was determined that the saturation coefficient of MFI zeolite in the form of Cs+ cation is equal to q=66 %
