Abstract: PROBLEM TO BE SOLVED: To provide a method capable of decomposing waste water containing hydroxylamine over a broad range of concentration and also decomposing it at a high reaction speed with a low residual concentration. SOLUTION: This method is for decomposing the hydroxylamine in aqueous solution, especially in waste water by treating it with an oxidizer, and as the ozidizer, alkali metallic salt of hypohalogenous acid, alkaline earth metallic salt of hypohalogenous acid or peroxomonosulfuric acid or peroxodisulfuric acid or its salt is used, and also the treatment with the oxidizer is performed at pH of
