Adsorption energetics of benzene vapors on activated adsorbent based on glycyrrhiza glabra root extract residues

Glycyrrhiza glabra root plant is mainly used in the pharmaceutical industry to obtain drugs. However, one of the important tasks is to obtain coal adsorbents with effective use of the remaining residues. We will have the opportunity to determine the full thermodynamic properties of the activated carbon adsorbent enriched with additional substances from the residues of the licorice root and to fully determine the adsorption properties of the obtained porous coal adsorbents using capillary and volumetric methods in a high-vacuum adsorption device and a high-sensitivity DAK 1-1 calorimetric apparatus. By determining the benzene adsorption isotherm, differential heat, entropy and equilibrium time of the obtained coal, the adsorption capacity of the new adsorbent, the location of the active centers, and the pore sizes can be described in detail.
