ZEOLITE-A SYNTHESIS FROM GLASS
ABSTRACT: Zeolite can be used
as ion exchanger, catalyst, and adsorbent.
One type of synthetic zeolites is zeolite-A which being developed to
overcome the weakness of natural zeolites for their difference of pore size.
This research is aimed to study the synthesized of zeolite-A from wasted
glasses as silica source. Hydrogel method was used by reacting sodium aluminate
into a sodium silicate solution. The gel formed was heated at 80°C for 8 hours
and to produce a white solid. The solid result were characterized by XRD, FTIR,
and AAS. The XRD analysis shown that the yield which formed closest to
zeolite-A structure was in concentrate variation of sodium silicate and sodium
aluminate of 1.05 : 1. This result also can be confirmed by FTIR analysis.
