This study explores the potential of sugarcane bagasse ash (SCBA) as a precursor in the extraction of sodium silicate. SCBA was obtained from sugarcane bagasse, residual waste from sugar industries. In the present study, sugarcane bagasse (SCB) was burnt with different temperatures 600 °C, 800 °C and 1000 °C for 2 hours and 4 hours and then the ash washed using hydrochloric acid (HCl) to remove metallic ions and impurities. The ash was characterized using X-ray Fluorescence (XRF). The result indicated that SCBA at 1000 °C for 4 hours using acid washing method gave the highest composition of silica which is 88.13%. Then, the ash with the highest silica composition was extracted using 3M of sodium hydroxide (NaOH) solution. During the process NaOH will bind with silicate to form sodium silicate (Na2SiO2) and water (H2O). The formation of sodium silicate was characterized and compare with commercial sodium silicate using Fourier Transform Infrared Spectroscopy. © 2017, Malaysian Society of Analytical Sciences.
