Abstract
Samples of natural zeolite from the Nor-Kokhb deposit (Armenia), as well as its chemically and thermally modified by the microwave method in comparison with the traditional method, were studied. It was shown that the process of microwave processing proceeds 3 times faster than the traditional one. X-ray diffraction analysis shows that the main mineral in the zeolite samples under study is clinoptilolite. According to the results of optical and EPR spectroscopy, the presence of Fe3+ ions in the framework and extraframework positions of the zeolite was revealed. The study of diffuse reflection spectra allows to conclude that zeolite is a wide-band material with a bandgap of 4.14 eV.
