Investigation of the characteristics of rolled scale with magnetic properties to determine its effectiveness as an adsorbent

One of the tasks of applied physics is to develop new methods for the use of condensed media, which are waste from various industries. In this case, several problems are solved, both related to ecology in its various applications, and to the production of various elements using physico-chemical processes. The paper considers rolling scale, which is formed in large quantities during the operation of metallurgical enterprises. One of the possible options for recycling rolled scale (recycling) is related to the possibility of its use as a sorbent in liquid purification and filtration systems. Morphological, chemical, and phase features of rolled scale are considered to determine its potential for sorption activity. Using spectral studies, a comparative analysis of magnetic and non-magnetic fractions was carried out, and differences in the content of iron-containing phases and impurity elements were revealed. It is established that the microstructure and composition of the material are determined by the conditions of its formation and directly affect the adsorption characteristics. The presence of magnetite and a porous structure contributes to the formation of an active surface for the deposition of chemically active elements on it, such as phosphorus, zinc and other dangerous elements that are not removed by mechanical filtration.
