Resumo
In this study, ash fromsugarcane waste was used in the synthesis of biosilica using alkaline extraction followed by acid precipitation.
Different parameters that could influence the silica particle synthesis were evaluated. The ash and synthesized biosilica were
characterized by a combination of spectroscopic and chemical techniques such as XRD, XRF, SEM, particle size analyser, N2
adsorption analysis, TGA, and FTIR. The best condition for biosilica production was achieved with fusion method and aging
temperature of 80∘C for 1 h during gel formation. X-ray powder diffraction pattern confirms the amorphous nature of synthesized
silica.The purity of the prepared silica was 99% silica which was confirmed bymeans of XRF.Theexperimental data suggest that the
sugarcane waste ash could be converted into a value-added product, minimizing the environmental impact of disposal problems.
