Bromate is a disinfection by-product that is formed when Ozone reacts with naturally occurring Bromide in drinking water. Bromate is a known animal carcinogen and has also been listed as a group 2B toxin: probable human carcinogen. The U.S. EPA Method 300.1 employs conductivity as the means of detection which works well for most anions. However, the method is nonspecific and coeluting interferences cannot be identified. The more recent U.S. EPA Method 317.0 utilizes a Bromate specific reagent in a post-column reaction. This allows for a very specific and sensitive assay for Bromate in complex matrices.
