Fenton氧化对硝基苯酚过程中Fe^2＋/Fe^3＋的氧化还原机制
Redox mechanism of Fe^2＋/Fe^3＋ during Fenton＇ s oxidation of p-nitorphenol
摘要
Abstract
During the process of Fenton＇ s degradation of p-nitrophenol （PNP） , the concentration of fer- rous ion was kept to be a high level following a rapid oxidation and reduction. Intermediates play an important effect on redox of Ferrous and Ferric. Intermediates hydroquinone and benzoquinone form a redox system, con- vert ferric to ferrous irons. Through analyzing the changes of intermediates during the Fenton＇ s oxidation, it was found that intermediates benzoquinone and hydroquinone play an important role in the catalytic reduction of ferric ion. This study further elucidates the Fenton＇ s oxidation mechanism of p-nitorphenol from the perspective of transformation between ferric and ferrous ions.关键词
