Standard Test Methods for
Iodide and Bromide Ions in Brackish Water, Seawater, and
Brines1

This standard is issued under the fixed designation D 3869; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope*

1.1 These test methods2 cover the determination of soluble
iodide and bromide ions, or both, in brackish water, seawater,
and brines. Four test methods are given as follows:

1.1.1 Test Method A for both Iodide and Bromide Ions—
Volumetric, for concentrations from 0.2 to 2000 mg/L iodide
and from 5 to 6500 mg/L bromide (Sections 7-15).

1.1.2 Test Method B for Iodide Ion—Colorimetric, for
concentrations from 0.2 to 2000 mg/L iodide (Sections 16-25).

1.1.3 Test Method C for Iodide Ion—Selective electrode, for
concentrations from 1 to 2000 mg/L iodide (Sections 26-34).

1.1.4 Test Method D for Bromide Ion—Colorimetric, for
concentrations from 40 to 6500 mg/L bromide (Sections
35-44).

1.2 Test Method A is intended for use on all brackish waters,
seawaters, and brines that contain appreciable amounts of
iodide or bromide ions or both. Test Methods B, C, and D,
because of their rapidity and sensitivity, are recommended for
the analysis of brackish waters, seawaters, and brines in the
field and in the laboratory.

1.3 Samples containing from 0.2 to 2000 mg/L of iodide or
5 to 6500 mg/L of bromide may be analyzed by these methods.

1.4 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 applica
