Natural zeolites are recognized as a fairly effective filtering material for the purification of various special waste and municipal waters. The aim of the study was to characterize heulandite-clinopti-lolite-type zeolites of Georgian, Kazakh and Armenian origin selected for the creation of new bacte-ricidal zeolite filter materials for purification and decontamination of water from various sources. According to chemical composition and X-ray diffraction data, the sample from the Rkoni plot of the Tedzami-Dzegvi deposit, Georgia, is a sodium form of high-silica heulandite mixed with a small amount of chabazite, the zeolite from the Chankanay deposit, Kazakhstan, is a mixture of calcium heulandite and chabazite, and the zeolite from the Nor-Kokhb deposit, Armenia, is a typical calcium clinoptilolite. Powder X-ray diffraction patterns show a high content of zeolite phase (70-90%) and determine the main inorganic impurities; the presence of a developed system of micropores is confir-med by Fourier transform infrared spectra; the samples are also characterized by different developed systems of mesopores with a maximum diameter of 120 nm.
