AN43227: Speciation of Bromine Compounds in Ozonated Drinking Water using Ion Chromatography and Inductively Coupled Plasma Mass Spectrometry
DescriptionBromate and brominated organic acids are generated by ozonation of bromide in municipal disinfection processes. The brominated compounds are toxic so compliance monitoring is required. Here four bromine species, including bromate are determined in drinking water using IC coupled to ICP-MS according to a modified U.S. EPA Method 321.8. The ions are separated by IC using a KOH gradient on an IonPac AS19 column. Then the eluting species are detected and quantified by ICP-MS down to ng/L concentrations with negligible spectral interferences using Kinetic Energy Discrimination (KED).
