摘要：

The semiconductor photocatalyst, platinised titanium dioxide, Pt/TiO2, is used to promote the destruction of bromate ions to bromide and oxygen by 254 nm ultraviolet light. The kinetics of bromate removal are first order with respect to [BrO3-] and are inhibited, although not completely, by competitive adsorption by other anions, including bromide and sulfate ions. The Pt/TiO2 can be used not only as a powder dispersion, but also as a thin film in a flow reactor for the destruction of bromate ions. Copyright (C) 1996 Elsevier Science Ltd
