芳香烃（AH）是存在于大多数环境基质中的有毒环境污染物。本文综述了从各种环境基质中去除 AHs 的高级氧化过程（AOP）。深入讨论了单环烃（BTEX）和多环芳烃（PAH）及其衍生物的各种 AOP。大多数 AOPs 可有效去除水生环境中的 AHs。对各种 AHs 降解的比较研究表明，AHs 的氧化在很大程度上取决于芳香环的数量和连接到环上的官能团。在含有氯离子、亚硝酸盐离子和硝酸根离子的真正污染水中形成 AH 的卤化物和硝化衍生物似乎是在实际系统中使用 AOP 的一个挑战。酚类化合物、醌、醇类和脂肪族酸是 AH 氧化过程中形成的重要副产物，由活性氧（ROS）对其富电子中心的攻击引发。总之，AOPs 是从不同环境基质中去除 AHs 的适应性方法。基于过硫酸盐的 AOPs 作为 AHs 的原位化学氧化应用于土壤相去除。此外，AOP 的组合将是避免或尽量减少意外或其他有毒中间产物并获得 AH 快速氧化的决定性解决方案。

Advanced oxidation processes for the removal of mono and polycyclic aromatic hydrocarbons – A review

Aromatic hydrocarbons (AHs) are toxic environmental contaminants presented in most of the environmental matrices. Advanced oxidation processes (AOPs) for the removal of AHs in the account of complete mineralization from various environmental matrices have been reviewed in this paper. An in-depth discussion on various AOPs for mono (BTEX) and polyaromatic hydrocarbons (PAHs) and their derivatives is presented. Most of the AOPs were effective in the removal of AHs from the aquatic environment. A comparative study on the degradation of various AHs revealed that the oxidation of the AHs is strongly dependent on the number of aromatic rings and the functional groups attached to the ring. The formation of halogenated and nitrated derivatives of AHs in the real contaminated water containing chloride, nitrite, and nitrate ions seems to be a challenge in using the AOPs in real systems. The phenolic compounds, quinone, alcohols, and aliphatic acids are the important byproducts formed during the oxidation of AHs, initiated by the attack of reactive oxygen species (ROS) on their electron-rich center. In conclusion, AOPs are the adaptable method for the removal of AHs from different environmental matrices. The persulfate-based AOPs were applied in the soil phase removal as an in situ chemical oxidation of AHs. Moreover, the combination of AOPs will be a conclusive solution to avoid or minimize unexpected or other toxic intermediate products and to obtain rapid oxidation of AHs.
