TL;DRAbstract

PCBs represent an important class of organic pollutants, due to their toxicity and ubiquity in contaminated sites. They are found in the environment mainly as a result of uncontrolled disposal of used oils and transformers. PCBs are refractory to most of current remediation technologies such that only thermal treatments can be effective in removing PCBs from contaminated soils. Advanced oxidation processes (AOPs) have become one of the most interesting and promising remediation techniques. Their operational principle is based on the idea of generating a pool of oxidizing species in the subsurface environment. The different AOP processes differ simply in the way this pool is produced. In Fenton’s reaction hydroxyl radical (OH) is generated by an iron-catalyzed reaction. The present work deals with the treatment of a PCB-contaminated soil, collected from a dump near Rome, by Fenton’s reagent. The soil was a complex matrix characterized by a very high organic matter (TOC = 6.57%), with an
