| Abstract: | Pure and high crystalline low silica X-type zeolite with Si/Al ratio of 1 was synthesized under specific hydrothermal conditions. After preparation and characterization of Na form of the zeolite (Na-LSX) from the synthesized zeolite, Na cations were exchanged by three alkaline earth cations. The amount of the exchanged cations per 1 g of the zeolite for each cation was determined by wet chemical method. Among the various prepared samples, those containing approximately equal amount of different cations were selected and characterized by XRD, IR, and XRF techniques. TGA/DTG/DTA and XRD techniques were employed to investigate thermal behavior of the cation exchanged zeolites. |
