Bromate is a harmful environmental contaminant and a suspected human carcinogen that is increasingly found in drinking water (categorised as class 2B carcinogens). Although bromate is not a natural constituent of water, it is introduced through various industrial and chemical processes, as well as water disinfection itself. The use of chemicals like potassium bromate, hypochlorite’s, processes like ozonisation being the chief contributors. There are many techniques available to quantify bromate ion. However, many of the techniques does not provide sufficient sensitivity and selectivity. Ion exchange chromatography is one of the best techniques to quantify bromate ion present in drinking water. It is a cost-effective and efficient technique for detecting bromate in water samples at sub-ppb levels. By using a pre-concentration column, higher sensitivity can be achieved without the use of expensive detectors like UV-vis or mass spectrometers and colouring chemicals. This approach not only makes the process more affordable but also ensures that even very low concentrations of bromate (0.1 ppb), well below the maximum permissible levels set by various agencies (~1.5 ppb), can be accurately quantified. This could be substantially helpful in achieving better quality and safety of drinking water.
