The bromate anion, BrO −3, is a bromine -based oxoanion. A bromate is a chemical compound that contains this ion. Examples of bromates include sodium bromate, (NaBrO3), and potassium bromate, (KBrO3). Bromates are formed many different ways in municipal drinking water.
drinking-water regulations. The determi-nation of the concentration of bromate is correspondingly a prerequisite measure for the elimination of risks for consumers’ health. The bromate concentration in drinking water can be determined, for example, by means of ion chromatography in con-junction with conductivity measurement.
To determine sub-μg/L concentrations of bromate in drinking water and higher ionic strength matrices without postcolumn derivatization, a two-dimensional IC technique (AN 18710) was developed that uses a Dionex IonPac AS19 column in the first dimension, and a Dionex IonPac AS24 column in the second dimension, followed by conductivity detection. 2.
1 sty 2002 · A spectrophotometric method has been developed based on the reaction between bromate and methylene blue in acidic conditions, for concentrations from 4 to 50 μg/l of bromate. It allows the monitoring of ozonation and the control of bromate formation in final drinking water on-site.

In ozonated bottled water, the average level of bromate was 18 μg/litre, with a range of 4.3–37.3 μg/litre (Health Canada, 1999). Haag & Hoigné (1983) and McGuire et al. (1990) reported a range of 60–90 μg/litre in ozonated water.
dissolved bromate in drinking water. The method should fulfil the analytical requirements of the Council Directive 98/83/EC (referred in this report as the Drinking Water Directive, DWD). The method is based on ion chromatography followed by post column reaction and ultraviolet detection.
