Bromide occurs in varying amounts in ground and surface waters of coastal areas from seawater intrusion and sea-spray precipitation. Under normal circumstances, the bromide content of most drinking waters is small, seldom exceeding 1 mg/L. Even levels of <100 μg/L can lead to formation of bromate or brominated by-products in disinfected waters. Industrial and oil-field brine discharges can contribute to the bromide in water sources.
Bromide ion-selective electrodes (ISE) are used to measure bromide in food products, beverages, plants, soils, and as an indicator in titrations. The following products include portable and benchtop ISE meters that can display bromide results in a choice of concentration units. Other products include calibration standard, ISA, and halide polishing strips for the halide solid state pellet.
