A mechanism has been established for the formation of active centers on the surface of activated waste of alumina production in Ukraine, as well as the composition and structure of new composite reagents. The main regularities of using the obtained reagents in the technology of water purification from inorganic and organic substances of various types and origin and the operating characteristics of the reagents obtained during water purification are determined. Mechanisms and regularities of heterogeneous processes of acid-thermal activation of solid substances, sorption, biosorption and catalytic phenomena in multicomponent aqueous media have been revealed for the first time. It has been established that inorganic (heavy metal ions), natural and technogenic organic compounds are isolated and trapped respectively by 95% and 98%.
