摘要
当向加入过氧化氢的有机废水中(pH值调节至3滴加硫酸亚铁溶液时发现,产生具有强烈刺激性气味的气体,与臭氧的气味相近,由此推断在Fenton反应中可能有臭氧存在。根据臭氧作为一种强的氧化剂,与碘化钾水溶液反应可游离出碘,碘遇淀粉呈蓝紫色颜色反应的原理,对Fenton反应的机理进行了分析,设计了验证实验。结果表明:吸收瓶中确实出现蓝紫色颜色反应,从而确定Fenton反应产生臭氧。该现象的发现,对今后研究Fenton试剂的反应机理有着重要的意义。
By dropping ferrous sulfate solution to the organic waste water which added hydrogen peroxide,pH=3, a strong irritating smell of gas was found to be produced,and the gas is similar to the smell of ozone.To inference: in the Fenton reaction, there is may ozone be produced. Ozone is a strong oxidizing agent, reaction with potassium iodide aqueous solution can be to free iodine, iodine case of starch was blue-violet color reaction principle. According to this principle ,design the verification experiment, and analyzed the mechanism of Fenton reaction. The results showed that,the absorption of the bottle is indeed a blue-violet color reaction, so the Fenton reaction can produce ozone. The discovery of the phenomenon has an important significance to the reaction mechanism of Fenton reaction.
