摘要

Fe2+的再生直接决定Fenton体系产生的能力。选取羟胺、对苯二酚、对苯醌、亚硫酸钠4种典型添加剂，通过分析不同改性Fenton体系中Fe2+浓度、H2O2浓度、氧化还原电极电位（ORP），揭示了Fe2+再生机制的差异，并进一步分析了不同添加剂与体系中H2O2及·OH的反应情况。结果表明：NH2OH能快速使Fe2+再生，但伴随其消耗，Fe2+浓度不断降低。对苯二酚、对苯醌具有相似效果，两者均可大大强化Fe2+的再生。与NH2OH不同，两者在体系中可迅速建立醌循环，持续还原Fe3+，且以两种物质或其组合均可建立循环。与上述机理均不同，Na2SO3会先与·OH及H2O2反应，因而不能有效还原Fe3+。实验还发现添加剂均存在与·OH的反应，其中Na2SO3还会消耗H2O2。

Abstract

The regeneration of Fe2+ can have a marked effect on·OH production in Fenton system. Hydroxylamine hydrochloride

hydroquinone

p-benzoquinone and sodium sulfite were used as typical additives. Different regeneration mechanisms of Fe2+ were revealed by analysis of Fe2+ concentration

H2O2 concentration and oxidation-reduction potential (ORP) as well. Furthermore

reactions between additives and H2O2 and·OH were also explored. Results demonstrated that Fe2+ was regenerated by hydroxylamine quickly

but concentration of Fe2+ gradually decreased with the consumption of hydroxylamine. Hydroquinone and p-benzoquinone exerted similar effect on Fenton system

resulting in enhanced regeneration of Fe2+. Quinone cycle could be built once they were added to Fenton system. Therefore

the concentration of Fe2+ could maintain a relatively high level in a long period. Quinone cycle can be established by one of the two substances or their mixture. Sodium sulfite reacted with·OH and H2O2

which contributed to a poor performance on Fe3+ reduction.
