Abstract—The adsorption properties of peat modified by mechanical activation in the presence of iron oxide
hydroxide were studied. Based on the results of the determination of adsorption activity and microcalorimetric
studies, it was established that physical absorption processes predominate on the interaction of the modified
peat sorbents with a model organic substance and the aqueous solutions of metal salts. It was demonstrated that
new types of sorbents with high sorption properties can be obtained based on peat mechanically activated in the
presence of water treatment wastes
