The results of adsorption of methylene blue from an aqueous solution on various samples of Fe+3 intercalated clays of the Navbakhor Deposit are presented. Comparative studies of the applicability of the Langmuir, Freundlich, and Dubinin-Radushkevich models for describing experimental adsorption isotherms of modified clays and their heat-treated forms at different pH values of the medium are presented. The Dubinin-Radushkevich isotherm model was used to calculate the free energy of methylene blue adsorption on intercalated systems
