Abstract

Abstract:

In this study, we presented a method based on ion chromatographic separation and ICP-MS detection for the determination of two existing forms of bromine in beverage, i.e., BrO3－ and Br－. The limits of detection of the presented method were 0.1μg/L for BrO3－ and 0.2μg/L for Br－. Spike recovery tests were carried out to evaluate the accuracy and precision of this method, and average recoveries for BrO3－ in 3 different matrices spiked at 3 levels ranged from 88.1% to 106.4%, with a relative standard deviation from 1.52% to 3.83% (n = 6). This method was used to analyze some commercial beverages, and no BrO3 － was detected in any of them.

Key words: IC-ICP-MS, beverage, bromate ion, bromide ion
