PHOTO OXIDATION OF HUMIC ACID IN AQUEOUS SOLUTION CATALIZED BY TIO 2 FILM
|
Abstract:
The photocatalytic oxidation of humic acid(HA) in aqueous solution using TiO 2 film as a catalyst was studied in compared to a dispersion system, in which the suspended TiO 2 particles were difficult to be separated and recovered. The method showed a good application perspective. The effects of the photosources, surface modifications of TiO 2 film and pH value of HA aqueous solution on photocatalytic oxidation efficiencies were investigated. The involved mechanism were discussed.
