dc.description.abstractThe use of natural raw materials for synthesis zeolite is considered to have more economic advantages, but special treatment is needed to remove some impurities such as metals. This study aims to synthesize zeolite using Maredan natural clay as a source of Si and Al through reflux method. The synthesis was started from the leaching process using 3 M sulfuric acid by adjusting the post-leaching atmosphere to pH 2 and 4, then calcined at 750ºC for 3 hours. Post-calcined clays were aged at 80ºC using 5 M NaOH with a stirring speed of 300 rpm for 3 hours, then followed by a reflux process at 100ºC for 8 hours. The solids from this synthesis were characterized using FTIR. FTIR data shows a double ring vibration D4R and D6R at a wavelength of 550-600 cm-1. These two types of vibrations correspond to the functional groups of the sodalite type zeolites. The acid site of the zeolite can be determined by FTIR analysis using pyridine adsorption, which shows the presence of Bronsted and Lewis acid sites at wave numbers 1540-1545 cm-1 and 1419-1544 cmen_US
