چکیده
|
Rice husk is an abundant agricultural residue, comprising cellulose, lignin, and silica# here, the possibility of silica extraction from rice husk of babolsar (north of iran) through a chemical route has been studied# amorphous precipitated silica was extracted from rice husk ash during three successive stages, namely decarbonization, dissolution and acid precipitation# xrd and xrf results confirmed the production of high purity amorphous silica# moreover, it was observed that it is possible to produce silica with both sulfuric acid and hydrochloric acid, but precipitation with sulfuric acid is more appropriate#
