Abstract

The oxidation effects of an ozone treatment using naphthalene (NAP), phenanthrene (PHE), pyrene (PYR) and a mixture of these polycyclic aromatic hydrocarbons (PAHs) adsorbed on solid phases were studied. Due to ozonation, a decrease of the applied concentrations of each of the investigated compounds with respect to their molecular weights occurred (up to 86% for NAP, 73% for PHE and 50% for PYR). After ozonation, the formation of o-phthalaldehydic acid, o-phthalaldehyde, o-phthalic acid, oxalic acid, acetic-acid, formic acid, and diphenic acid was observed as oxidation products. Dependent on dosage, ozone was even able to oxidize the PAH to carbon dioxide and water to a certain extent.
