Abstract:
The utilization of household furniture glass waste as a source of silica is used to synthesize zeolite. This research aimed to obtain synthetic zeolite from glass waste and to determine the effect of hydrothermal temperature on crystallinity and zeolite type. The synthesis begins with extracting silica from glass waste using sodium carbonate. Then it is reacted with sodium aluminate to produce a gel. The hydrothermal process was carried out for 4 days at various temperatures, namely 80?, 100?, and 120?. Products are analyzed FTIR, XRD, and GSA. The product at a hydrothermal temperature of 100? has the best crystallinity and belongs to the phillipsite mineral type where 2? = 28.424°; 17.814°; 21.837°; 12.052°; 33.693°, and has the largest surface area of ??147.22 m2/g.
