Abstract
The article describes a comparative analysis of the structural and energy parameters of fresh and used sand and AC grade sorbent by the water vapor adsorption method using a BELSORP MAX porometer. The processing of adsorption-desorption isotherms was performed in the BELMaster MicrotracBEL Corp software package with the calculation of the specific surface area, total volume, average pore size and adsorption energy of water vapor using the BET, Langmuir and Dubinin-Astakhov (DA) methods. An increase in the specific surface area and porosity of the used sand and sorbent of the AC brand is observed, which indicates structural changes during their operation: an increase in the specific surface area and porosity. The obtained results allow us to draw a conclusion about the possibility of reusing spent sand and AC grade sorbent after regeneration, as well as the need to take into account changes in their properties when designing treatment systems.
