Study of Calcination Temperature and Concentration of NaOH Effect on Crystallinity of Silica from Sugarcane Bagasse Ash (SCBA)

Abstract:

Sugarcane bagasse ash is a by-product produced from bagasse burning in sugarcane industry. SCBA contain high concentration of silica and some other elements such as aluminum, iron and alkaline earth oxide. In this study, an approach of ash preparation, acid washing and acid leaching have been proposed to extract silica from different concentration of sodium hydroxide, NaOH at 3M and 4M were prepared for silica extraction. The ash obtained after calcinations was characterized using X-ray Fluorescent (XRF) and the microstructure of silica particles were characterized by X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR). The x-ray fluorescent (XRF) result shown that the highest composition of silica obtained is 88.13% at temperature 1000°C for 4 h. At 1000°C, the peaks for silica quartz appeared at multiple angle compared to that of at 600°C. Moreover, significant intensity level difference was also observed. However, different concentration of sodium hydroxide (NaOH) used for silica extraction had shown insignificant effect on crystallinity level of silica quartz obtained. Keywords: Sugarcane bagasse, silica, biomass waste, renewable resources
