Abstract: Silica was extracted from sugarcane bagasse and used as corrosion inhibitor for copper plate. Sugarcane bagasse was treated with acid and then heated at different heating temperature. The silica content of 89.12% was achieved by HCl treatment and then heating the bagasse at 800oC for 3 hours. The silica was then characterized using scanning electron microscope (SEM-EDX) and X-Ray Fluorescence (XRF). Furthermore, the silica was used to as a corrosion inhibitor for copper plate. The corrosion inhibition efficiency of silica was attained 100% using both 1M HCl and 1M NaOH electrolytes as measured using the weight loss measurements after 3 days of exposures. It was found that the silica act potentially as corrosion inhibitor for copper plate in acidic and basic medium.
