Analcime is a fairly widespread zeolite in the territory of Georgia and other countries, but its practical application is limited due to the peculiarities of its compact structure with small pores and irregular channels. This work describes a method developed by us for hydrothermal recrystallization of analcime into a widely used ion exchanger of the LTA type in the form of micrometric crystals or nanosized crystals, depending on the synthesis conditions. Silver-, copper-and zinc-containing analcimes and synthetic LTA zeolites with bacteriostatic activity were obtained by ion exchange. It has been shown that the highest bacteriostatic activity is possessed by a silver-containing synthetic zeolite, and analcimes enriched with relatively cheap copper and zinc exhibit activity sufficient for practical use in water treatment, paper production and other applications.
