Similar term(s): inorganic bromide, bromide compounds, bromide ion.
Br-. An inorganic bromide anion. Also used to describe any compound
(usually a bromide salt) that contains the Br- ion, such as sodium bromide
Inorganic bromide is widely distributed in the environment. It is commonly
found in natural waters, that is, streams, lakes and reservoirs. Br- comes from
wastewater discharges, agricultural run-off (mainly from soil fumigation) and
run-off from roads. The bromide ion is a precursor to water disinfectant by
products when ozone or possibly hypochlorite (bleach) are used as disinfectants,
and therefore needs to be controlled. The bromide ion itself is sometimes used
as a water disinfectant because, in water it forms hypobromous acid (HOBr)
considered as a strong disinfectant.
