Abstract

Adsorption processes on the surface of modified diatomites of the Akhmatovsky Deposit in the Penza region were studied. Freundlich adsorption isotherms are constructed, quantitative characteristics of the values of adsorption of copper ions on the surface of modified and unmodified sorbents are obtained, as well as the values of empirical coefficients that allow us to assess the degree of suitability of this model for describing adsorption processes.
