Description: The effect of g-Al₂O₃ modification with the cations K⁺, Rb⁺, and Cs⁺ on its textural characteristics and acid–base and adsorption properties with respect to water was studied. The kinetics of water vapor adsorption on the test samples was described by the Gluckauf equation to model processes occurring under the influence of internal diffusion. The adsorption capacity of the modified materials was approximately 30–40% higher than that of the unmodified Al₂O₃.
