| Abstract: | Acid properties of the surface of copper-, cobalt- and iron-containing alumosilicate sorbents prepared by the method of destructive epitaxial precipitation we investigated. Concentration and strength of the proton acid centers of the samples is studied in comparison with the parent natural alumosilicate sorbent based on the opokas of the Prikaspii lowland of Astrakhan’ region. |
