title: Photolysis of PAHs in aqueous phase by UV irradiation.
abstract: The photooxidation of polycyclic aromatic hydrocarbons (PAHs) was investigated in an aqueous ethanolic solution irradiated with a medium-pressure mercury lamp in laboratory photoreactors equipped with a quartz immersion well. Degradation photolysis of fluorene was more efficient than sensitized photolytic oxidation in the presence of TiO2 suspensions. Photolysis kinetics was dependent on molecular weight and the presence and type of substituents. During the photolytic degradation of fluorene and its derivatives, 9-fluorenone and its corresponding derivatives, which were more resistant to photolysis, were formed.
