Bromate may be formed in water during ozonation when the bromide ion is present (Haag & Hoigné, 1983). Under certain conditions, bromate may also be formed in concentrated hypochlorite solutions used to disinfect drinking-water (IPCS, 2000). This reaction is due to the presence of bromide in the raw materials (chlorine and
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 (NaBrO 3) and potassium bromate (KBrO 3). Bromates are formed many different ways in municipal drinking water. The most common is the reaction of ozone and bromide: Br − + O 3 → BrO ...
Chemical fact sheets: Bromate. 18 May 2022. | Technical document. Download (58.6 kB) Overview. Chapter 12 of the Guidelines for drinking-water Quality (GDWQ) includes fact sheets on chemical contaminants, based on comprehensive review documents published by WHO.
1 sty 2004 · In drinking water, bromate (V) ions are formed as a by-product of bromide oxidation with ozone in the water disinfection process. Since BrO 3- ions are potentially cancerogenic, their...
Bromide can be involved in the reaction between chlorine and naturally occur-ring organic matter in drinking-water, forming brominated and mixed chloro-bromo by-products, such as trihalomethanes (THMs) and halogenated acetic acids (HAAs), or it can react with ozone to form bromate.
a cost-effective way for determining just bromate. 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
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.
