Impact/Purpose:
The environmental or health problem addressed by the study: Evaluated reactivity of bromine found in bromochloramine versus those found in bromamines A general description of the work and results: Experiments have been conducted to evaluate the reactivity of the bromine found in bromochloramine The long term importance or significance of the findings: Provides a new understanding of bromochloramine reactivity which will serve for the basis of updating kinetic models associated with chloramine chemistry in the presence of source water bromide Who would be interested in or could apply the results (e.g. program or regional partners, general public, local communities): Researchers and drinkingwater utilities trying to understand chloramine chemistry when bromide is present
Description:
The chloramination of bromide containing waters results in the formation of the bromine containing haloamines: monobromamine, dibromamine, and bromochloramine (NHBrCl). Many studies have directly shown that bromamines are more reactive than chloramines in oxidation and substitution reactions with organic water constituents because the bromine atom in oxidants is more labile than the chlorine atom. This work highlights the need reexamine what the true brominating agents are in chloraminated waters containing bromide.
