Аннотация:A new method for preparation of a composite based on graphene oxide and montmorillonite has been proposed. A comparative characteristic of the adsorption rate for montmorillonite, graphene oxide, and a composite based on them is given. It is shown that the composite has the best adsorption properties with respect to methylene blue. The samples have been studied by IR and Raman spectroscopies, SEM, X-ray powder diffraction, and TGA/DTA. The resulting composite material can be widely used as sorbents for organic dyes in an aqueous medium and organic solvents.
