Reaction rates of polynuclear aromatic hydrocarbons with ozone in water

Experiments were carried out, using stopped-flow spectrometry, to investigate the reaction rates of the polynuclear aromatic hydrocarbons (PAH), pyrene, phenanthrene, and benzo(a)pyrene with ozone in water. The second-order rate constants are 40,000, 15,000 and 6000 dm3 per mol per second respective...

Summary:Experiments were carried out, using stopped-flow spectrometry, to investigate the reaction rates of the polynuclear aromatic hydrocarbons (PAH), pyrene, phenanthrene, and benzo(a)pyrene with ozone in water. The second-order rate constants are 40,000, 15,000 and 6000 dm3 per mol per second respectively over pH 1-7. The corresponding half-lives in the presence of 0.1 mM ozone at pH 7 are less than a second.
