文摘

In this work, clinoptilolite hydrogen forms are obtained from the Khonguruu zeolite locality (Republic of Sakha, Russia) using hydrochloric acid solutions of different concentrations. The chemical composition is identified via X-ray spectral microprobe analysis and thermogravimetry. IR vibrational spectra of the alumino–silico–oxygen framework are studied in its dealumination and decationization. The effect of the aluminum content in clinoptilolite hydrogen forms on the intensity change and frequencies of the principal vibrational bands of alumino–silico–oxygen framework is established as well.Original Russian Text © A.M.
