| 摘 要： | 对超声波/零价铁协同降解硝基苯的作用机理进行了研究.结果表明,超声波与零价铁联用时有明显的协同效应.超声辐照有利于铁屑转化为Fe2+,并进一步氧化为Fe3+,不规整铁屑对超声空化有促进作用,在超声波/零价铁体系中存在Fenton反应,通过产生大量的·OH降解硝基苯,该氧化过程是硝基苯降解的主要途径之一.

| Abstract: | The mechanism of nitrobenzene degradation by ultrasound/aero-valent iron system was studied.The results showed that,ultrasound and zero-valent iron had obvious synergistic effect when they were used combinedly.Ultrasound irradiation could help convert iron scrap into Fe2+ and further oxidized it to Fe3+,meanwhile,irregular iron scrap could promote ultrasonic cavitation.As Fenton reaction existed in the ultrasound/zero-valent iron system,large amount of ·OH was produced,which could degrade nitrobenzene.The above oxidation process was one of the main ways for nitrobenzene degradation. |
