| 摘 要： | Fenton降解对硝基苯酚(PNP)过程中,Fe2+经历一个快速氧化后快速还原,最后在高浓度水平上保持稳定的变化过程。通过分析中间产物的变化过程,发现有机中间产物氢醌和苯醌构成一对氧化还原体系催化Fe3+向Fe2+的转化,本研究从Fe2+/3+转化机制的角度进一步明确了Fenton降解PNP的机理。 |

| Abstract: | During the process of Fenton’s degradation of p-nitrophenol(PNP),the concentration of ferrous 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,convert 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. |
| Keywords: | Fenton' s reagent p-nitorphenol reduction of ferric ion benzoquinone hydroquinone |
