Abstract
Zeolite is an abundant mineral in Indonesia, but is not maximally utilized. Natural zeolite possesses several properties, such as dehydration, adsorption, ion exchange, catalysis, and separation. In general, natural zeolite contains both organic and inorganic impurities that cover their pores. Thus, natural zeolite should be initially activated to improve its absorption. This study aimed to determine the effect of NaOH solution concentration, temperature, volume, and zeolite diameter on the adsorption capacity of zeolite. The highest adsorption capacity of 7.03% was obtained at the optimal concentration of 1.0 N NaOH solution (100 °C) with a volume of 50 mL at a diameter of 2.00 mm during chemical activation.
