文摘
Polycyclic aromatic hydrocarbons (PAHs) are a group of toxic pollutants in the environment. In this preliminary study, photolysis of fluorene, a three-ring PAH, in rainwater collected in Higashi–Hiroshima, Japan, was studied. The photolysis kinetic was observed to be of first order under our experimental conditions. It was found that the photolysis rate constant was approximately 0.091?min? with a half-life of 8.0?min. The photolysis kinetic of fluorene in rainwater was found to be very much faster than for particulate atmospheric PAHs reported in the literature.
