Abstract：
Advanced oxidation processes (AOPs) are widely used as efficient technologies to treat highly toxic and harmful substances in wastewater. Taking the most representative aromatic compounds (monosubstituted benzenes, substituted phenols and heterocyclic compounds) as examples, this paper firstly introduces their structures and the structural descriptors studied in AOPs before, and the influence of structural differences in AOPs with different reactive oxygen species (ROS) on the degradation rate was discussed in detail. The structure-activity relationship of pollutants has been previously analyzed through quantitative structure-activity relationship (QSAR) model, in which ROS is a very important influencing factor. When electrophilic oxidative species attacks pollutants, aromatic compounds with electron donating groups are more favorable for degradation than aromatic compounds with electron donating groups. While nucleophilic oxidative species comes to the opposite conclusion. The choice of advanced oxidation processes, the synergistic effect of various active oxygen species and the used catalysts will also change the degradation mechanism. This makes the structure-dependent activity relationship uncertain, and different conclusions are obtained under the influence of various experimental factors.
摘要：
高级氧化工艺（AOPs）被广泛用作处理废水中剧毒和有害物质的有效技术。以最具代表性的芳香族化合物(单取代苯，取代的酚和杂环化合物)作为例子，本文首先介绍了它们的结构以及以前在AOPs中研究的结构描述符，详细讨论了具有不同活性氧（ROS）的AOPs的结构差异对降解速率的影响。之前已经通过定量结构-活性关系(QSAR)模型分析了污染物的结构-活性关系,其中ROS是一个非常重要的影响因素。当亲电氧化物质攻击污染物时，具有供电子基团的芳族化合物比具有供电子基团的芳族化合物更有利于降解。而亲核氧化物种则得出相反的结论。高级氧化工艺的选择，各种活性氧和所用催化剂的协同作用也会改变降解机理。这使得结构依赖的活动关系不确定，在各种实验因素的影响下得到了不同的结论。
