In the present work Na-13X zeolite is exchanged with Sr(II), ions. The compositional analysis of the parent zeolite and the exchanged derivative has been carried out using Atomic Emission Spectroscopy - Inductive Couple Plasma, (AES-ICP). The percentage of exchange is the maximum for Sr2+. X-ray diffraction technique is used to determine the unit cell structure. This exchanged derivative is then used to prepare adsorbed derivatives with NO2 gas. The structural changes are studied by IR spectroscopy. Thermal studies of the parent zeolite, its exchanged derivatives and the adsorbed derivatives are carried out using Thermo Gravimetric Analysis (TGA).
