Outline of Final Research Achievements

Development of processes for converting rice husk ash discharged from rice husk power plant to functional materials was carried out. By mechanochemical treatment, crystalline silica contained in the rice husk ash transformed into amorphous silica, and a specific surface area of the treated rice husk ash increased. The treated rice husk ash showed high adsorption ability for methylene blue. In addition, a process of synthesizing allophane from rice husk ash has been developed. The synthesized allophane showed high adsorption ability for acetaldehyde.
