Chemical reduction methods for bromate ion removal

Abstract

Bromate ion (BrO3-) in drinking water is a concern to water utilities because of its toxicity - but also because new regulations have been promulgated to lower residual levels of BrO3- in finished water. This study evaluated sulfite ion (SO32-) and reduced iron (Fe2+) as potential removal agents for BrO3- ever a wide pH range. The experimental rate law for BrO3- removal using SO32- shows that the rate of removal decreases with increasing pH. The experimental rate law for BrO2- removal using Fe2+ shows that the rate of removal increases with increasing pH.
