Abstract

In this study, the thermal and structural properties of natural analcime zeolite obtained from the Çanakkale-KüçükkuyuAyvacık region and its cationic forms (HA, FeA, AgA and CuA) were characterized using a range of methods. These included X-ray fluorescence (XRF), X-ray diffraction (XRD), thermogravimetric analysis (TG), differential thermogravimetric analysis (DTG), differential thermal analysis (DTA) and specific surface area measurement techniques. Cationic forms were prepared by using 1 M HCl, 1 M Fe(NO3)3.9H2O, 1 M AgNO3 and 1 M Cu(NO3)2.3H2O solutions. Quantitative XRD analysis showed that the natural zeolite was mainly composed of analcime accompanied by quartz, feldspar, montmorillonite and amorphous substances. AgA and HA samples showed different thermal and structural behaviors due to their rearranged crystal structure and chemical composition. Adsorption properties of samples were determined by using adsorption isotherms and specific surface areas obtained by the Brunauer-Emmet-Teller (BET) method. The specific surface areas of the ion-exchanged analcime zeolites were found to be higher in comparison to natural analcime. Among all the modified forms, it was found that the Hform of the analcime sample has the largest surface area HA (41.88 m2/g).
