A brief review is completed on the chemical oxidation of PAHs contaminated soils. Previously, the adsorption and extraction processes are also documented and discussed. The tree main technologies reported in the specialised literature include the use of ozone, hydrogen peroxide (with or without ferrous iron addition) and high temperature pressurized water (both in sub- and super-critical conditions) in the presence of an added oxidant like hydrogen peroxide, oxygen, persulfate, etc. Each process is detailed by the influence of the main operating variables reported in the literature (i.e. presence of organic matter, soil type, reagents dosage, etc.), the kinetics and the description of integrated treatments (i.e. chemical oxidation + biodegradation).
本文对多环芳烃污染土壤的化学氧化进行了简要综述。此前，吸附和萃取过程也有记录和讨论。专业文献中报道的三种主要技术包括在添加过氧化氢、氧气、过硫酸盐等氧化剂的情况下使用臭氧、过氧化氢（添加或不添加亚铁离子）以及高温高压水（亚临界和超临界条件下）。文献中报道的主要操作变量（即有机物的存在、土壤类型、试剂用量等）的影响、动力学以及综合处理（即化学氧化+生物降解）的描述对每个过程都进行了详细说明。
