Polycyclic aromatic hydrocarbons (PAHs) represent a threat to human health and the environment. This review analyzes recent publications about the use of persulfate (PS) for the treatment of PAH-contaminated soils. The reviewed publications reaffirmed the versatility of this oxidant and the convenience of its use. Pollutants and PS concentrations, PS-activation methods, and combination with bioremediation in PS applications were considered. Several studies detected the formation of SO₄^.- and HO^. radicals, with relative amounts, depending on the experimental conditions. The main parameter considered to evaluate the evolution of the treatments was the concentrations of each PAH or the global value. The optimization of the methods was focused on the application and activation of PS. Recommendations for future investigations are included.

多环芳烃 (PAH) 对人类健康和环境构成威胁。这篇综述分析了最近关于使用过硫酸盐 (PS) 处理多环芳烃污染土壤的出版物。审查过的出版物再次肯定了这种氧化剂的多功能性和使用的便利性。考虑了污染物和 PS 浓度、PS 活化方法以及在 PS 应用中与生物修复的结合。几项研究检测到 SO ₄ ^.-和 H2O的形成^。自由基，相对量，取决于实验条件。考虑评估处理演变的主要参数是每种 PAH 的浓度或全局值。方法的优化集中在PS的应用和激活上。包括对未来调查的建议。
