The surface characteristics of the zeolites need to be known for their effective use especially, as ion exchanger, catalyst, and adsorbent. In this study, the morphological, mineralogical and surface properties of zeolites were investigated by some instrumental analyses such as X-ray diffraction pattern (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and Brunauer-Emmett-Teller (BET) methods. FTIR spectra proved the presence of silanol and bridged hydroxyls on the zeolite surface. The pore properties including surface area, pore volume, pore size distribution, and average pore diameter of the zeolites were determined by N2 adsorption at 77 K using the BET t-plot and density functional theory (DFT) methods. The pore size distribution showed that the zeolites include both micro and mesopores. The specific surface area of zeolites with different SiO2/Al2O3 ratios decreased as the Si/Al ratio increased. XRD Method was used to examine the crystal structures of zeolites and SEM was used to examine the particle structures. Surface acidity of heat activated zeolites was determined using two different methods. Information about the total amount of acid sites on the zeolites was provided by the n-Butylamine titration method. and FTIR spectra provided information about surface acidity.
