“…As is customary, the process of absorption of gaseous substances or substances from the liquid phase by liquids or solids is called sorption [1,2]. Depending on the aggregate state of substances, two types of sorption are distinguished: absorption -volumetric absorption of gas by a liquid; adsorption -absorption of a gaseous or liquid substance by a volume or surface of a solid [3].…”

This article outlines the outcomes of laboratory investigations focusing on the sorption behavior of Cr (III, VI), Zn, Ni, and Co on bentonite. The study encompasses a broad spectrum of solution pH levels and sortable component concentrations, aiming to unveil the states of micro-components in aqueous solutions. The research also addresses the identification of optimal chemical concentration conditions and the establishment of a sorption mechanism for these components on clay adsorbents based on bentonite. In aqueous solutions, the ions of these metals undergo hydrolysis, resulting in the formation of complex compounds. The study discerns that the sorption process on bentonite clays predominantly initiates at pH levels around 4-5 and concludes at pH exceeding 7.5-10. These findings shed light on the critical pH ranges where sorption reactions are most significant and highlight the cessation of sorption at elevated pH levels. The research contributes to a comprehensive understanding of the sorption dynamics between bentonite and metal ions, emphasizing the pH-dependent nature of these interactions. By identifying the optimal conditions for sorption and elucidating the underlying mechanisms, this study offers valuable insights into leveraging bentonite clay as an effective adsorbent for the removal of Cr (III, VI), Zn, Ni, and Co from aqueous solutions.

“…Today, the raw materials for the production of activated carbons are natural coals, peat, wood, nutshells, fruit pits, and others, which are charred in a neutral environment at a temperature of about 1000°C. As a result of the thermal decomposition of organic substances, inactive coal is obtained, which is processed by the method steam-gas activation [13,14]. Oxidation of coal at high temperatures leads to the burning out of carbon particles and the formation of a widely branched network of pores.…”

The article is devoted to the research of the chemical composition of coals. The main goal of the research is to choose the method of its enrichment. The authors established that after the enrichment of coal, the ash content sharply decreased due to the washing off of its inorganic part. The process of coal enrichment, at a ratio of 1:2 (coal: water) has a positive effect on reducing the ash content by 1.3 times. Based on the data obtained, it was found out that the enrichment process in the coal production adsorbents is necessary to reduce their ash content. Based on the research a technological scheme for obtaining a carbon adsorbent and solutions for their regeneration were proposed.
