Abstract

All advanced oxidation processes are characterized by a common chemical feature: production of OH radicals.

These radicals are suitable for achieving complete abatement and mineralization of pollutants. AOP usually operate at or close to ambient temperature and pressure. The potentialities offered by AOP can be exploited to integrate biological treatments by oxidative degradation of toxic substances, entering or leaving the biological stage. The usual two AOP are the Fenton process and photocatalysis.
