Synthesis of zeolite from diatomite was conducted by using dilute alkali, 0.15M and 0.3M NaOH solution. Preheating treatment at 70ºC for 6 hour before hydrothermal reaction at 170ºC was necessary for activation. The synthesis product was mordenite type zeolite. The zeolite has high capacity for VOCs adsorption, represented by formaldehyde and toluene.
