Scope

1.1 These multi-test methods cover the determination of the oxyhalides—chlorite, 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 these test methods for each analyte were as follows:

 

Range

Sections

Test Method A:
Chemically Suppressed Ion Chromatography

 

8 to 20

 Chlorite

5 to 500 µg/L

 

 Bromate

1 to 25 µg/L

 

 Bromide

5 to 250 µg/L

 

 Chlorate

5 to 500 µg/L

 

Test Method B:
Electrolytically Suppressed Ion Chromatography

 

21 to 31

 Chlorite

20 to 1000 µg/L

 

 Bromate

1 to 30 µg/L

 

 Bromide

20 to 200 µg/L

 

 Chlorate

20 to 1000 µg/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 these test methods. However, analysis of these ions is not the object of these test methods.

1.2 It is the user’s responsibility to ensure the validity of these test methods for waters of untested matrices.

1.3 These test methods are technically equivalent with Part B of U.S. EPA Method 300.1,2 titled “The Determination of Inorganic Anions in Drinking Water by Ion Chromatography.”

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. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
