The destruction of three polycyclic aromatic hydrocarbons (PAHs): benzo[a]pyrene, chrysene andfluorene in aqueous solution using advanced oxidation process H2O2/UV was investigated. The influence ofpH, initial hydrogen peroxide and radical scavenger concentrations on the reaction rate was studied. Theoxidation reactions most rapidly run in neutral and acidic solution at optimal hydrogen peroxide concentration(ca. 0.01 M). The degradation of benzo[a]pyrene and chrysene follows radical reaction, for fluorene themechanism is not clear. The rate constants of the hydroxyl radicals and selected PAHs reaction were foundto be 2.53×1010, 9.82×109 and 2.77×109M−1S−1 for benzo[a]pyrene, chrysene and fluorene, respectivel
