Standard Test Methods for Bromate, Bromide, Chlorate, and Chlorite in Drinking Water by Suppressed Ion Chromatography
The oxyhalides chlorite, chlorate, and bromate are inorganic disinfection by-products (DBPs) of considerable health risk concern worldwide. The occurrence of chlorite and chlorate is associated with the use of chlorine dioxide, as well as hypochlorite solutions used for drinking water disinfection. The occurrence of bromate is associated with the use of ozone for disinfection, wherein naturally occurring bromide is oxidized to bromate. Bromide is a naturally occurring precursor to the formation of bromate.1.1 This multi-test method covers the determination of the oxyhalideschlorite, bromate, and chlorate, and bromide, in raw water, finished drinking water and bottled (non-carbonated) water by chemically and electrolytically suppressed ion chromatography. The ranges tested using this method for each analyte were as follows: RangeSections Test Method A: Chemically Suppressed Ion Chromatography8 to 19 Chlorite5 to 500 x00B5;g/L Bromate1 to 25 x00B5;g/L Bromide5 to 250 x00B5;g/L Chlorate5 to 500 x00B5;g/L Test Method B: Electrolytically Suppressed Ion Chromatography20 to 30 Chlorite20 to 1000 x00B5;g/L Bromate1 to 30 x00B5;g/L Bromide20 to 200 x00B5;g/L Chlorate20 to 1000 x00B5;g/L 1.1.1 The upper limits may be extended by appropriate sample dilution or by the use of a smaller injection volume. Other ions of interest, such as fluoride, chloride, nitrite, nitrate, phosphate, and sulfate may also be determined using this method. However, analysis of these ions is not the object of this test method. 1.2 It is the userx0027;s responsibility to ensure the validity of these test methods for waters of untested matrices. 1.3 This test method is technically equivalent with Part B of U.S. EPA Method 300.1 , titled x201C;The Determination of Inorganic Anions in Drinking Water by Ion Chromatographyx201D;. 1.4 The values stated in either SI or inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.

Water quality - Determination of dissolved bromate - Method by liquid chromatography of ions (ISO 15061:2001); German version EN ISO 15061:2001
Water quality - Determination of dissolved bromate - Method by liquid chromatography of ions.
This International Standard specifies a method for the determination of dissolved bromate in water (e.g. drinking water, raw water, surface water, partially treated water or swimming pool water). Appropriate pretreatment of the sample, for example by elimination of chloride, sulfate, metals, preconcentration or dilution, gives a range of applicability of 0,5 μg/l to 1 000 μg/l dissolved bromate. The working range is restricted by the ion-exchange capacity of any preconcentration columns used and that of the separator column. Dilution of the sample to the working range may be necessary.
