Ozonation and Advanced Oxidation Processes of Polycyclic Aromatic Hydrocarbons in Aqueous Solutions - A Kinetic Study

Abstract

The kinetics of ozonation and advanced oxidation processes (AOP) of seven polycyclic aromatic hydrocarbons (PAH) (fluorene, anthracene, phenanthrene, pyrene, fluoranthene, benzo(a)pyrene, benzo(ghi)perylene) has been under study. Ozonation was shown to be quite effective for destruction of PAH, especially in neutral media. The PAH evaluation rate has been lower when advanced oxidation processes were applied comparing with simple oxidation. The rate constants for different chemical oxidation processes of PAH are presented.
