SINTESIS DAN KARAKTERISASI ZEOLIT FAUJASIT DARI LIMBAH BATUBARA OMBILIN DENGAN METODA ALKALI HIDROTERMAL AIR LAUT
ABSTRACT: Zeolite synthesis
using Ombilin coal fly ash at low temperature with alkaline hydrothermal process
has been carried out. The used Fly ash was melted by NaOH at a temperature of
550°C.Alkaline hydrothermal processes in zeolite synthesis performed with
variations of temperatureat 35°C , 45°C and 60°C . The zeolite that obtained
was characterized by using Fourier Transform Infra Red (FT - IR), X - Ray Diffraction
(XRD) , Scanning Electron Microscopy (SEM) in combination with EDX . The
characterization results showed the formation of zeolitewere better when an
increasing in temperature processes and the use of sea water as a solvent. On
the use of seawater, were obtained sodalit zeolite with the chemical formula Na8(Al6Si6O24)Cl2
.
