Comparison the Properties of Zeolite Nay Synthesized by Different Procedures

Aveen H. Matti, Kafia M. Surchi

This research was aimed to compare the morphology, crystallinity, chemical composition Si/Al and Na/Al of seven samples of NaY zeolite prepared by different procedures and different silicon sources .Fourier Transform Infrared Spectrometry (FTIR), Scanning Electron Microscopy, Energy Dispersive analysis (EDA), X-Ray Fluorescence (XRF), XRay Diffraction (XRD) were selected to characterize the prepared samples. The FTIR results indicated that the position, height, and width of the peak are nearly identical for all synthesized samples. According to SEM results, the frame work of homoionic sodium form NaY zeolite was not widely affected, via treatment with NaCl. The EDS output indicated that, Si/Al were in the following order: NaY type 1 ˃ USY ˃ NaY type 3 ˃ NH4Y ˃ NaY type 2 ˃ Regenerated NaY ˃ Homoionic sodium form. XRF analysis show that the major components of laboratory synthesized zeolites are SiO2, Al2O3, Na2O and H2O, along with a small quantity of CaO and trace amounts of K2O, Fe2O3, P2O5 and MgO.
