OVERVIEW

Ozonation, a commonly used treatment to remove contaminants and inactivate microbes in drinking water, can result in the formation of bromated, a disinfection byproduct, via the oxidation of naturally occurring bromide. Whereas bromide is non-toxic, bromated 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 bromated at sub-ppb levels using ion chromatography in combination with inductively coupled plasma followed by detection with mass spectrometry. Advantages of this method include significantly reduced risk of contamination, stable and quantitative bromated recovery, and high salt tolerance.

KEY LEARNING OBJECTIVES:

- Learn the importance of bromine speciation in drinking water and current regulatory methods available for analysis

- Learn the benefits of combining ion chromatography with inductively coupled plasma mass spectrometry for speciation analysis
