Maredan clay is synthesized to produce zeolites that can be utilized as adsorbents in adsorbing CO2. This research aims to synthesize zeolite from Maredan clay due to its high SiO2 and Al2O3 content. Maredan clay was characterized using XRF to determine the oxide content in it. The method used in the synthesis of zeolite is alkaline hydrothermal fusion by mixing NaOH solids and Maredan clay 1:1…
