Abstract

By cation exchange for clinoptilolite tuff from the Khonguruu deposit (Yakutia) the Mg-, Ca-, Sr-, Bamodified heulandite-clinoptilolite zeolites are obtained. Based on the data of powder X-ray diffraction and thermal analyses, the properties of these modifications are characterized. Using nitrogen cryosorption, the specific surface areas are determined. Found that the specific surface areas of the cationic modifications obtained increase with the ion charge.
