摘要
文章以水溶性偶氮染料甲基橙为对象,进行了超声降解实验研究。实验结果表明,甲基橙初始体积质量、溶液体系pH值及超声时间对甲基橙降解效果均有影响,并通过实验证明,甲基橙的超声降解途径为自由基氧化,且甲基橙分子结构中-N=N-显色基团断裂程度较苯环的断裂程度明显。
Sonochemical degradation of methyl orange, a kind of azo dye, was carried out. The experimental results show that the initiative concentration of methyl orange, the pH value of the solution and the time of reaction have an immediate effect on the sonochemical degradation. It is also found that hydroxyl radical oxidation for methyl orange degradation is the major reaction mechanism, and moreover, -N=N- of methyl orange in water is more easily ruptured than phenyl of the methyl orange in aqueous solution.
