The formation of bromate (BrO3−) from bromide ion in water during ozone treatment of the water is inhibited by inclusion of a compound of formula I: where each of R1 and R2 is an oxygen-containing electron-withdrawing substituent effective to resonance stabilize an alkoxy radical of compound I, and R3 is an alkyl, aryl, or aralkyl group. The water may be further treated with an additional oxidant such as hydrogen peroxide. The compound of formula I is effective to inhibit formation of bromate from bromide present in the water, without impairing the oxidative remediation of the water. |
