Abstract

The rate of ozone decomposition Controls the yield of bromate and is influenced by water quality characteristics and water treatment parameters. Hypobromite ion (OBr) and hydroxyl (HO) radical concentrations affect the extent and rate of bromate formation as well, Through the use of butanol as an HO radical scavenger, delineation of indirect HO radical and direct molecular ozone oxidation pathways are inferred. Approximately 75% of the bromate formation is controlled by HO radical mechanisms, while the remain- der forms via molecular ozone mechanisms alone. Oxidation of bromine appears to be a criticai oxidation step in either pathway.
