Abstract
Gamma-irradiation effect on the kinetic parameters of the cation exchange reactions of Fe2+, Co2+ and Ni2+ ions on H-Mordenite has been studied. Kinetic analysis of the results according to the various theoretical models showed that the best fir of data is obtained of both non-irradiated and irradiated H-Mordenite with low doses from 2.2.106 to 4.6.106 Gy with three-dimensional diffusion controlled reaction (D3), while the best fit is obtained for the 2-dimensional diffusion controlled reactions (D2) by increasing the radiation dose to 5.5.106 Gy. These investigations have shown that the possible reason for such behavior have been analyzed on the basis of g-irradiation may be caused desorption of the adsorbed ionic species.
