title: Photocatalytic oxidation of nitrite in water to nitrate.
abstract: It is found that the nitrite in water is converted into nitrate by irradiation in the presence of oxygen and titanium dioxide which acts as a catalyst. As nitrate is a less hazardous contaminant, this method might be worth investigating further for the treatment of water.
