title: Catalytic ozonation for degradation of 2, 4, 6-trichloroanisole in drinking water in the presence of gamma-AlOOH.
abstract: Results show that catalytic ozonation with gamma-AlOOH can substantially enhance the removal effectiveness of 2, 4, 6-trichloroanisole (TCA) in drinking water. Scavenging of radicals tests reveals that the improved 2, 4, 6-trichloroanisole degradation is due to the enhanced generation of hydroxyl radicals. The uncharged surface hydroxyl groups on gamma-AlOOH in water can induce aqueous ozone decomposition to generate hydroxyl radicals. The catalytic activity of gamma-AlOOH decreased as thermal treatment temperature increased.
