Silica removal by alkaline hydrogen peroxide treatment to enhance the conversion of rice straw to sugars

The massive production of rice straw could eventually lead to uncontrolled air pollution due to open burning activity. In this study, the rice straw was treated with alkaline hydrogen peroxide (AHP) to remove silica as well as to maximize the hydrolysis of the treated rice straw. Thus the study aime...
