- 摘要：考察了光照/无光照条件、体系中不同种类的蒽醌、Fe(Ⅲ)、自由基淬灭剂、H2O2及其含量变化等对罗丹明B降解特征的影响.结果表明:含氧化敏感官能团结构的蒽醌类有机质在光照作用下,促进了Fenton反应的进行,使得罗丹明B脱色程度得到加强.这主要是因为蒽醌类有机质和模拟太阳光耦合作用过程驱动了体系中铁不同形态 之间的持续循环,为Fenton反应过程中关键活性物种羟基自由基的生成提供所了所必须的Fe(Ⅱ).
- Abstract：The current study mainly investigated the influences of the simulated solar light irradiation, different kinds of quinone containing redox sensitive chemical structure, ferric iron, radical quencher and hydrogen peroxide on the characteristics of Fenton decolorazation of Rhodamine B. The results showed the simulated solar irradiated organic matters containing quinone structure enhanced the Fenton reaction process and consequently strengthened the degree of Rhodamine B decolorazation. The acceleration of Fenton reaction process was attributed to the recycle between the two species of iron, Fe(Ⅲ) and Fe(Ⅱ),which was driven by the interaction process between the organic matters containing quinone structure and simulated solar light irradiation.
