Physically synthesis and characterization of zeolite nanoporous for sodium coated / Nor Azura Che Mahmud

Different size of zeolite nanoporous were fabricated from zeolite microparticle using wet grinding method. The zeolite nanoporous formation attributed to the bowl mill generation of mechanical stress that fractured zeolite microparticle into smaller fragments. Five samples with different time of grinding which are 2 hours, 4 hour, 6 hours, 8 hours and original zeolite with fixed in mass of zeolite and rotational speed of milling have been used in this project. The result from this hybrid process suggest that it can be used to fabricate differing size of zeolite nanoporous. The coating process was prepared by using immersion method. All samples were coated with two different weight percent of zeolite which is 0.1 and 0.5 weight percent simultaneously. Particle Sizer, Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Ultraviolet/Visible (UV-Vis) Spectroscopy and Energy Dispersive Spectrometry (EDS) were employed to characterize the samples. The optimum grinding time of zeolite nanoporous sample obtained is 2 hours with 0.1 weight percent of sodium coated. Structural analysis indicates that the value of absorbance of sodium depends on the porosity of the samples.
