The degradation of three selected polycyclic aromatic hydrocarbons (PAHs): benzo[a]pyrene (BAP), chrysene (CHR) and fluorene (FLU) in aqueous solution using ozone was investigated in the pH range 2-9. Mathematical and kinetic models of this heterogeneous process was established and it was used for identification of kinetic parameters of the reactions. The rate constants of direct reaction of hydrocarbons with ozone were estimated and they were equal to: (6.16š0.14)-104; (6.97š0.21)-103 and 62.7š0.8 m'kmol's1 for BAP, CHR and FLU, respectively. The rate constants of the hydroxyl radicals and PAHs reaction were found to be (1.54š0.06)10'°; (1.26š0.10)-1010 and (1.57š0.04)-108 m'kmol's' for BAP, CHR and FLU, respectively.
