Popis: A reagent KCN solution and an industrial wastewater containing CN − can be efficiently degraded photocatalytically in aqueous TiO 2 semiconductor dispersions. The disappearance of CN − , consumption of O 2 , formation of OCN − an intermediate and ultimate mineralization to CO 2 and N 2 were quantitatively determined. A large-scale photoreactor (5 l) was also manufactured, which is an excellent device for the photodecomposition of a large amount of cyanide.
