ABSTRACT: The availability of an economic source of amorphous silica has been a challenge in Nigeria over the years. In this study, characterization of silicon dioxide (SiO2) and its extraction from bamboo shoot were carried out. Dried bamboo shoots were calcinatd at 600 ºC for 5 hr using a muffle furnace to obtain bamboo ash (BSA). Silica gel was produced by digesting BSA with sodium hydroxide solution to form sodium trioxosilicate (IV) solution. The solution was treated with hydrochloric acid solution to form silica gel at pH 7.0 and then, dried. The yield of 40.60% silica obtained had attrition, moisture content, porosity and bulk density of 50.90%, 2.53%, 1.06 and 1.05 g/m3, respectively. Characterization using FT-IR technique has indicated the presence of silanol (Si-OH) and siloxane (Si-O-Si) functional groups in high frequency stretching and low frequency bending of the silica. Besides, Scanning Electron Microscope (SEM) analysis revealed amorphous structure of SiO2 prepared from BSA. Thus bamboo shoot can serve as an economical source of amorphous silica.
