    Research Progress on Promoting the Chemical Oxidation Degradation of Pollutants by Organics

    • 摘要: 通过向体系中添加天然有机物以提高污染物化学氧化降解效率的技术近年得到广泛关注。研究表明,有机物既可通过促进过渡金属还原、络合过渡金属等机制加速经典氧化反应进程,也可直接活化氧化剂构建高级氧化体系。基于典型有机官能团对污染物化学氧化降解过程的促进作用,金属-有机框架材料得以发展及应用。该文综述了促进氧化反应的常见有机物种类及作用机制,以期为化学氧化技术进一步发展提供参考依据。

       

      Abstract: The improvement of pollutant oxidation degradation efficiency by adding natural organic catalysts has attached widespread attention in recent years. Studies have shown that organic compounds can accelerate the process of classical oxidation reactions by promoting the reduction of transition metals or complexing transition metals, and can also activate oxidants directly to generate oxidative free radicals. Based on the promotion of typical organic functional groups on the chemical oxidative process, metal-organic framework has been developed and applied widely. This manuscript reviews common types of organic-promoted oxidation reactions and their mechanisms, so as to improve the chemical oxidation technology and put forward some plausible advice.
