    摘要:

    活性氧物种是一类具有氧化能力的含氧自由基或含氧的非自由基衍生物。利用活性氧物种降解环境污染物是绿色高效的污染控制和环境修复手段。然而活性氧物种种类繁多,产生方式多种多样,在环境污染物降解转化中的作用机制也不尽相同。深入了解环境污染物降解转化中不同活性氧物种的产生和作用机制意义重大。本文综述了近年来活性氧物种(羟基自由基、超氧阴离子自由基、单线态氧和过氧化氢)在环境污染物去除方面的最新研究进展,介绍了几类常见的活性氧物种及其产生途径和检测方法,归纳和总结了活性氧物种在大气环境净化、有机废水处理和有害微生物杀灭等方面的应用,同时对今后活性氧物种在污染控制和环境修复方面的应用进行了展望。

    Abstract:

    Reactive oxygen species (ROS) are a class of oxygen free radicals or non-radical derivatives of oxygen with oxidizing ability. Utilizing ROS to degrade environmental pollutants is one of the greenest and most effective chemical means for pollution control and environmental remediation. However, there are different types and various generating-routes of ROS, and the mechanisms of environmental pollutant degradation and removal are distinguishing. It is significant to further understand the production and action mechanism of different ROS in environmental pollutant degradation and transformation. This article reviews recent research progress on ROS (hydroxyl radical, superoxide anion, singlet oxygen and hydrogen peroxide) for environmental pollutants removal in recent years and introduces several common ROS and their generating pathways and detection methods. We also summarize the applications of ROS in air purification, organic wastewater treatment, bacterial inactivation and finally discuss the major problems about ROS for environmental pollutants degradation and prospect the application of ROS in pollution control and environmental remediation.
