Textural Properties Characterization for NaX and FeX Zeolites by Nitrogen Adsorption-desorption Technique


The zeolite's textural properties have a significant effect on zeolite's effectiveness in the different industrial processes. This research aimed to study the textual properties of the NaX and FeX zeolites using the nitrogen adsorption-desorption technique at a constant low temperature. According to the International Union of Pure and Applied Chemistry, the adsorption-desorption isotherm showed that the studied materials were mixed kinds I/II isotherms and H3 type hysteresis. The Brunauer - Emmett - Teller isotherm was the best model to describe the nitrogen adsorption - desorption better than the Langmuir and Freundlich isotherms.The obtained adsorption capacity and Brunauer - Emmett - Teller surface area values for NaX were greater than FeX.
