STUDY OF THE PHYSICO-CHEMICAL CHARACTERISTICS OF MATERIALS OBTAINED FROM IRON-CONTAINING WASTE FROM THE METALLURGICAL INDUSTRY AND THEIR SORPTION PROPERTIES

The paper presents results of the study of the physico-chemical properties of synthesized magnetic sorbents are presented. It is shown that the process of obtaining magnetic nanoparticles affects the sorption mechanism of these materials. The effect of high-temperature treatment on the physico-chemical properties of the obtained particles is investigated. The values of the static exchange capacity of magnetic sorbents in relation to cationic surfactants were determined.
