摘要: 大量研究表明, 可溶性有机质因自身的醌呼吸结构能够作为氧化还原体来催化转化多种有机和无机化合物, 然而其影响机制尚未完全了解, 因此需要更深层次的研究以阐明限制可溶性有机质介导化学和生物转化有机污染物的机理。本文以硝基芳香化合物为例, 全面阐述了其化学和生物降解机理以及可溶性有机质作为氧化还原电子穿梭体对其还原转化过程介导作用的研究进展;回顾了各种因素影响可溶性有机质催化转化硝基芳香化合物的效果, 并寻求氧化还原效率较高的可溶性有机质促进污染物的消减, 从而提高可溶性有机质对催化降解硝基芳香化合物的实际应用性。

关键词: 可溶有机质, 氧化还原介质, 电子穿梭, 硝基芳香化合物

Abstract: A large number of studies have documented that dissolved organic matter (DOM), with its special structural features in the quinone respiration process, can act as redox mediator to catalyze and transform a variety of organic and inorganic compounds, while the influence of the mechanism is not entirely understood. It is significant to conduct more researches to clarify the chemical and biological mechanisms restraining mediation of dissolved organic matter in transformation of organic pollutants. The chemical and biological mechanisms of nitro aromatic compounds degradation and the catalytic effect of transformation process when DOM acts as the redox electron shuttle mediator are summarized. Meanwhile, the effect of various factors for the catalytic conversion of dissolved organic nitroaromatic compoundsis reviewed. Future researches should concentrate on seeking the dissolved organic matter with higher redox efficiency to reduce pollutants, thus improving the practical applications of redox mediators in catalytic degradation of nitro aromatic compounds.

Key words: dissolved organic matter, redox mediators, electron shuttle, nitroaromatic compounds
