Daftar Isi:
- Zeolitic materials were prepared from PLTU Ombilin coal fly ash by hydrothermal synthesis method at pH 14 and seawater as a solvent, the crystallization was canducted at high temperature 150oC for different times ( 6, 12, 18 and 24 hours). The zeolitic material obtained was characterized by X-ray diffraction (XRD), Fourier transformed infrared (FT-IR) spectroscopy, and has charateristics of zeolite sodalite (SOD), a detailed morphological characterization of synthesis products with Scanning electron microscopy (SEM) was carried out to investigate crystal morphology of SOD zeolites.
