Abstract
The influence of KrCl excilamp UV radiation (7nr = 222 nm) on the biodegradation of polycyclic aromatic hydrocarbons (PAHs: anthracene, phenanthrene, and naphthalene) by activated sludge treatment has been investigated using electronic absorption and fluorescence spectrometry and chromatography methods. The revealed final photoreaction products of a quinine structure indicate that a hydroxylation reaction is involved in the mechanism of PAH photodegradation. The loss of separate PAHs in hexane after the action of the KrCl excilamp has been determined. Preliminary irradiation improves the efficiency of PAH biodegradation by activated sludge treatment in comparison with biodegradation.
