Ozonation, a commonly used treatment to remove contaminants and inactivate microbes in drinking water, can result in the formation of bromate, a disinfection byproduct, via the oxidation of naturally occurring bromide. Whereas bromide is non-toxic, bromate is toxic and carcinogenic. The extreme difference in toxicity necessitates the use of methods that readily distinguishes between these two species. Bromine speciation in drinking water is required by major regulatory bodies worldwide, including the U.S. Environmental Protection Agency.

This webinar will focus on the quantification of bromide and bromate at sub-ppb levels using ion chromatography (IC) in combination with inductively coupled plasma mass spectrometry (ICP-MS). Advantages of this method include stable and quantitative bromate recovery and high salt tolerance.
