Abstract

Lynde Type-A (LTA) zeolite is one type of zeolite that has various uses including as an adsorbent, catalyst, ion exchanger, and molecular sieve. Generally, LTA zeolites are produced from commercial chemicals and natural materials such as natural zeolites using the hydrothermal method which takes up to 24 hours to synthesize. The use of the hydrothermal method in the synthesis process is proven to produce zeolites with good quality but takes a long synthesis time, therefore it is necessary to innovate by comparing the hydrothermal synthesis method and the Microwave-assisted Hydrothermal Synthetic Route through various tests. The use of microwave as a synthesis method was carried out with a power of 200 watts and variations in synthesis time of 10, 20 and 30 minutes. After being analyzed using XRF (X-ray Fluorescence) the synthesis product has a SiO₂/Al₂O₃ ratio of 1.69 then through FTIR (Fourier Transmission Infra Red) testing found the characteristic of LTA zeolite in the form of double rings at wave numbers 550-600 cm^-1, through XRD (X-Ray Diffraction) testing obtained the highest percent relative crystallinity of LTA of 83,61%, through BET analysis (Brunaur, Emmet And Teller) found the highest surface area of 11.055 m²/gr in the 30-minute synthesis product, and through SEM analysis (Scanning Electron Microscopy) displayed zeolites in the form of rhombic crystals similar to previous LTA zeolites.
