Extraction of Silica from Sugarcane Bagasse, Cassava ...

2017-9-23  Silicon is more abundant in MS than in CP with least amount observed in SB. Extraction of silica from ashes obtained after calcination has been established from previous researches [3, 14]. The presence of metals (e.g. Al) that could form amphoteric oxides should be taken into consideration as this may affect the final purity of the silica.
