In this study, we used Pb2+ cation exchanged zeolites as adsorbents due to their porous structure. Adsorption of n-propyl mercaptan on modified LTA and (3A, 4A) zeolites were studied by FTIR (Fourier Transform Infrared) Spectroscopy and AAS (Atomic Absorption Spectrometer) is used to measure the amount of metal cations on mentioned zeolites. SEM-EDX (Scanning Electron Microscope-Energy Dispersive X-Ray) graphics are used to monitor the differences on the surface. Cation modified zeolites change their characteristic properties for adsorption. LTA type zeolites when modified by Pb2+ cation tend to adsorb n-propyl mercaptan.
