WebThe formation of bromate during ozonation is strongly dependent on the characteristics of the water to be treated and the amount of ozone contacting the water. The following lists the important variables for bromate formation: 1) Bromide concentration Given that bromide is oxidised by ozone to bromate, an increase in bromide WebBromide is readily oxidized to bromate when raw water is disinfected for municipal supply using ozone, and bromate is a suspected human carcinogen (U.S. Environmental Protec-tion Agency, 2006). The conversion of bromide to bromate during ozonation is influenced by factors such as the con-centration of dissolved bromide, pH of the source water, and

Potassium bromate is produced when bromine is passed through a hot solution of potassium hydroxide. This first forms unstable potassium hypobromite, which quickly disproportionates into bromide and bromate: 3BrO (aq) → 2Br (aq) + BrO 3(aq) Electrolysis of potassium bromide solutions will also give bromate. Both processes are analogou…
