Decomposition reactions of aqueous CN<SUP>-</SUP> ions by TiO<SUB>2</SUB> photocatalyst, ozone and/or hydrogen peroxide were investigated. The principal findings obtained are as follows:<BR>1) The presence of dissolved oxygen was necessary to decompose aqueous CN<SUP>-</SUP> ions photocatalytically. CN<SUP>-</SUP> was oxidized to CNO<SUP>-</SUP> with TiO<SUB>2</SUB> catalyst, and then to CO<SUB>3</SUB><SUP>2-</SUP> and NO<SUB>3</SUB><SUP>-</SUP>. Oxidation reaction of CNO<SUP>-</SUP> to CO<SUB>3</SUB><SUP>2-</SUP> and NO<SUB>3</SUB><SUP>-</SUP> was far slower compared to that of CN<SUP>-</SUP> to CNO<SUP>-</SUP>. Photocatalytic oxidation reaction of CNO<SUP>-</SUP> at pHs 7 and 10 proceeded distinctly faster compared to that at pH 12. <BR>2) Although ozone oxidation of CN<SUP>-</SUP> took the same paths as photocatalytic reactions, but it was faster than that of photocatalytic routes. Combined use of photocatalyst and ozone for the decomposition of CN<SUP>-</SUP> was more efficient.<BR>3) Decomposition product of CN<SUP>-</SUP> with hydrogen peroxide was found as CNO<SUP>-</SUP> and N<SUB>2</SUB>. Joint use of hydrogen peroxide and photocatalyst promoted reaction of CN<SUP>-</SUP> to N<SUB>2</SUB>.
