“…Organomineral sorbents based on heat-activated coal and mineral products (coal sludge, cake, and coal mineral pulp) have recently come into spotlight. They are highly selective due to forming active adsorption foci; besides, using them will help dispose of the dumps of waste [1][2][3][4][5][6][7]. When producing fossil coal, enrichment inevitably generates considerable amounts of waste in the form of coal sludge or cake and pulp.…”

This paper dwells upon finding the specific surface area of cake, a coal enrichment waste, exposed to electroplasma treatment; the goal is to make an organomineral porous material to be used as a sorbent for wastewater treatment. The research team used a monomolecular Langmuir adsorption model and surface tension of the surfactants before and after adsorption at the interface of solution and solid adsorbent. Another process considered herein was thermal activation of substances in the electroplasmic reactor for making organomineral porous materials from coal cakes. The paper presents the resulting specific surfaces area of the organomineral sorbent thus produced. Thus, the waste of flotation, i.e. coal cake, is fundamentally suitable for making porous substances by thermal destruction in an electroplasma reactor.
