文摘

Utilization of the agro-industry waste for the extraction of nano silica particles. Extraction method is simple, achievable at 80 °C and at normal atmospheric pressure. FTIR revealed presence Si–O–Si and Si–OH functional groups. Proposed method eliminate the use of template/surfactant for silica extraction and avoid acid washing prior to processing. Synthesized pure amorphous silica (99%) has good industrial and commercial value.
