Testing for Bromide in Water, Waste Water & Salt Water

Bromide Measurement

Bromide is a Chemical compound commonly used as a tracer for the detection of fertilizers within the natural environment. In many cases bromide is used as an alternative to Chloride as there are less occurrences of bromide within the natural environment. Bromide is detected using a sensor called an ISE (ion selective electrode).

Bromide is found in seawater, brine water and rock formation water. Bromide is a bromine atom with an ionic charge of -1 (Br-). In seawater its concentration is commonly measured at 65 mg/l. Seafood’s and deep-sea plants have high levels of bromide. In addition to this, bromine is used as a disinfectant for cooling towers and swimming pools. In freshwater the concentration of bromide is generally 0.05 mg/l.
