摘要: Decomposition reactions of aqueous CN- ions by TiO2 photocatalyst, ozone and/or hydrogen peroxide were investigated. The principal findings obtained are as follows:1) presence dissolved oxygen was necessary to decompose photocatalytically. oxidized CNO- with catalyst, and then CO32- NO3-. Oxidation reaction NO3- far slower compared that CNO-. Photocatalytic oxidation at pHs 7 10 proceeded distinctly faster pH 12. 2) Although took the same paths photocatalytic reactions, but it than routes. Combined use photocatalyst for decomposition more efficient.3) product found N2. Joint promoted
