چکیده
To increase the amount of ferulic acid adsorbed on a acid-silica composite, which is expected to be applied as UV-protection material, method for preparing composite by using an anti-solvent precipitation was investigated. Mesoporous silica dispersed in 50% ethanol solution acid, and water added poor solvent; resultant adsorption five times higher with added. The diffuse reflectance spectrum prepared acid-mesoporous only showed absorption ultraviolet light no visible light. This confirmed that into pores powder, not its surface.
