Abstract
Polycyclic aromatic hydrocarbons (PAHs), naphthalene, phenanthrene, anthrac ene, and pyrene were irradiated in acetonitrile (CH3CN) and in dichlorometh ane (CH2Cl2) on individual PAH compounds and in the presence of other compo unds. The observed photodegradation of PAHs was dependent on the structure of the compound, Anthracene and pyrene were the most photoreactive in dichl oromethane: with total degradation after 0.5 h irradiation for anthracene a nd 1.5 h for pyrene, The decomposition of PAHs was faster in dichloromethan e than in acetonitrile.
