STUDY OF PHYSICOCHEMICAL PROPERTIES OF ADSORBENTS BASED ON POTASSIUM HUMATE AND USE IN HYDROGEN STORAGE

This research is based on the investigation of the physicochemical properties of adsorbents based on potassium humate. During this study, we evaluated the structure, characteristics, and adsorption capacity of these materials. Potassium humate served as the main starting material, and we used a series of high-temperature carbonization and activation processes to produce the adsorbents we were investigating. We characterized the surface structure, porosity, and elemental composition of the resulting adsorbents using techniques such as cryogenic scanning probe microscopy and scanning electron microscopy (SEM). We determined the specific surface area of the adsorbents in terms of surface volume using gas absorption techniques, specifically the Brunauer-Emmett-Teller (BET) method. The findings reveal a significant improvement in the porosity and adsorption properties of activated adsorbents. Most of these materials have a high specific surface area, which indicates their exceptional adsorption capacity. These porous carbonaceous adsorbents, obtained through the methods described, are well-suited for purifying industrial wastewater and can act as effective gas adsorbents, including for hydrogen storage. Further research and experimentation hold promise for even greater improvements. Based on the results obtained through these methods, potassium Humate-derived adsorbents emerge as a versatile and technologically feasible raw material with wide-ranging applications.
