Role of radical reactions in benzo[a]pyrene degradation by advanced oxidation processe
Języki publikacji
Abstrakty
Degradację benzo[a]pirenu w roztworach wodnych przeprowadzono czterema metodami pogłębionego utleniania: H[2]O[2]/UV, O[3], O[3]/UV i O[3]/H[2]O[2], badając wpływ pH mieszaniny reakcyjnej i obecności inhibitora reakcji rodnikowych na szybkość procesów. Wyznaczono stałe szybkości reakcji benzo[a]pirenu z rodnikami hydroksylowymi i ozonem. Oszacowano udział reakcji bezpośrednich i rodnikowych w badanym procesie.
Degradation of benzo[a]pyrene in aqueous solutions was carried out using four systems of advanced oxidation processes: H[2]O[2]/UV, O[3], O[3]/UV and O[3]/H[2]O[2]. The influence of reaction mixture pH and the presence of radical reactions inhibitor on the process rates was examined. The contributions of direct and radical reactions in the studied systems were evaluated.
