Hydrogen Sulfide Adsorption improvement of Bayah Natural Zeolite

Thomas Agus Bayu Prasetyo, Bambang Soegijono


Hydrogen sulfide adsorption performance of sonicated natural zeolite in the Ferric chloride hexahydrate solution has been studied.  In this research natural zeolite exposed with high intensity ultrasonic waves for 40 minutes, 80 minutes and 120 minutes. Qualitative analysis and characterization of modified zeolite carry out with X-ray diffraction, Infrared spectroscopy, BET adsorption desorption, LAS particle size analysis and scanning electron microscopy prior and after H2S adsorption.  Natural zeolite phase are clipnotilolite and mordenite phase with 0.99%wt and 0.512 x 10-3 %wt respectively.  By adding 5gr FeCl3.6H2O and ultrasonic exposure, zeolite chemical and physical properties such as chemical composition, particle size, surface area and pore radius are improved.  Hydrogen sulfide %wt adsorption effectiveness showing that modified zeolite higher 70-117% comparing with unmodified zeolite.
