The studies on dehydration reaction mechanism of irradiated solid acid - nanostructured sodium - bentonite clay

Abstract

Research findings can offer data and a theoretical framework for a quantitative examination of the bentonite dehydration mechanism. The reasons for changes in pore’ water under the influence of gamma rays in vacuum and in the presence of oxygen was discussed using TGA and DTA, FT-IR spectroscopy. It was revealed that dehydration and pore characteristics are mutually dependent. A question about the associated evolution of dehydration pore‘s water in nanostructured sodium – bentonite clay under the influence of ionizing rays with and without oxygen has been comparatively studied. The article is devoted to a discussion of how ionizing radiation, passing through nanoclays, produces, or rather begins to produce, chemical effects. It was used Infrared spectroscopy as the method for determining structural responses of natural clay from the Alpoid deposit in the Republic of Azerbaijan, to gamma rays exposure. It was found that under influence of ionizing rays in vacuum obtained hydrogen peroxide. It is of great interest for the study of the dehydration reaction mechanism and its role in formation of H2 under gamma irradiation.
