Drastic increases of silica purity were observed in samples treated with sulfuric acid and the ionic liquid at 99.6% and 99.5%, respectively. Furthermore, the ionic When compared to industrially used methods, silica recovered from waste treated with alkali gives high purity silica at a low temperature. By dissolving waste in sodium hydroxide (NaOH) solution, Na 2 SiO 3 could be easily obtained, and silica can be quickly precipitated from solution using sol-gel process [9] .Agricultural and industrial waste-derived mesoporous silica
