Determination of Trace Concentrations of Chlorite, Bromate, and Chlorate in Bottled Natural Mineral Waters
5 Feb 2015Bottled water must be disinfected to remove pathogenic microorganisms and ensure it is safe for human consumption. Reactions between disinfectants and natural matter in the source water can result in the production of undesirable disinfection byproducts, such as bromate, which is potentially harmful to humans. This method describes the use of a high-capacity Thermo Scientific™ Dionex™ IonPac™ AS9-HC column with a carbonate eluent and large loop injection to achieve a method detection limit (MDL) of 1.4 μg/L bromate.
