Abstract
In this work a simple process for the production of high purity biogenic amorphous SiO2 derived from rice husk ash have been studied. Rice husk ash obtained from heat treatment of rice husk and citric acid leaching of rice husk at 700 o C for 6 h. Improvement of purity SiO2 from rice husk ash conducted by precipitation technique. The precipitated SiO2 particles obtained were characterized by x-ray fluorescence (XRF) analysis, Fourier transform infrared (FTIR) spectroscopy, and x-ray diffraction analysis (XRD). The XRF result shows that the high purity of biogenic amorphous SiO2 obtained is 99.258 %. The XRD result shows the silica have amorphous phase and for the FTIR results shows bending and stretching vibration of Si-O and Si-O-Si.
