The Fenton and Fenton-like reactions are important in biology because they are a major source of oxidative stress. The reactions also feature in advanced oxidation technologies to remediate organic pollutants. Unfortunately, these reactions are often simplistically viewed as affording only OH˙ radicals as the active species. Indeed, a variety of additional oxidizing intermediates form, including OR˙, Mn+2Lm, MnLm−1(O2H−), MnLm−1(O2R−) and CO3˙−, depending on the system. Under physiological conditions, CO3˙− is probably the major oxidizing intermediate. The Fenton and Fenton-like reactions feature in oxidative stress and are central to advanced oxidation technologies to remediate organic pollutants. The reactions are often simplistically taught to afford only hydroxyl radical as the active oxidant. Yet, this is just one of many possible oxidants and is probably not the major oxidant formed under biological conditions.

重新检查芬顿和类芬顿反应

Fenton 和 Fenton 样反应在生物学中很重要，因为它们是氧化应激的主要来源。这些反应还以高级氧化技术为特色，以修复有机污染物。不幸的是，这些反应通常被简单地视为仅提供 OH˙ 自由基作为活性物质。事实上，根据系统的不同，会形成多种额外的氧化中间体，包括 OR˙、Mn+2Lm、MnLm−1(O2H−)、MnLm−1(O2R−) 和 CO3˙−。在生理条件下，CO3˙− 可能是主要的氧化中间体。Fenton 和类 Fenton 反应以氧化应激为特征，是修复有机污染物的高级氧化技术的核心。通常简单地教导反应仅提供羟基自由基作为活性氧化剂。然而，
