Chemical oxidation and advanced oxidation technologies are importantprocesses for the abatement of refractory and/or toxic pollutants in wastewaters. Thespecies participating in advanced oxidation technologies are powerful radicals, suchas the hydroxyl radical, HO?, which can attack virtually all organic compounds atvery high reaction rates. In this chapter, oxidative technologies, such as permanganate,ozonation, Fenton and related processes, electrochemical oxidation,γ-radiolysis and electron-beam treatment, nonthermal plasma, persulfate, wet airoxidation, supercritical water oxidation, ultrasound, zero-valent iron, ferrate, waterphotolysis under vacuum ultraviolet, periodate, chlorine and heterogeneousphotocatalysis, some of them combined with UV light, are briefly described,together with examples of their applications. The most important and recent papersare cited together with review papers. These oxidative technologies can processwastewaters resistant to conventional treatments and are complementary to them.
