Wheat husk an abundantly available agriculture waste in wheat growing areas, having an average of 9 per cent of silica that can be retrieved as “Amorphous Silica” under controlled burning conditions. Extracting amorphous silica from wheat husk in commercial incinerators is difficult because of improper burning conditions and incomplete burning of inside heaps of husk, where availability of required oxygen can not be ensured. Potassium permanganate upon heating liberates oxygen and may provide the required oxygen to the husk during oxidation process. In present study the effect of potassium permanganate has been studied for extracting amorphous silica under controlled burning conditions. Wheat husk was treated with various dosages of potassium permanganate before subjecting to the tube furnace. The treated wheat husks were then heated at various temperatures. The ashes obtained were analyzed analytically and by XRD and FTIR. It has been observed from XRD patterns that KMnO₄ has helped in formation of amorphous silica where as FTIR spectra showed no carbon formation in treated samples where as analytical analyses confirmed better formation of amorphous silica.
