2、n American National StandardStandard Test Methods forIodide and Bromide Ions in Brackish Water, Seawater, andBrines1This standard is issued under the fixed designation D 3869; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the yea
3、r of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript 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, sea
4、water, 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 IonColorimetric, for concentrations from 0.2 to 20
5、00 mg/L iodide (Sections 16-25).1.1.3 Test Method C for Iodide IonSelective electrode, for concentrations from 1 to 2000 mg/L iodide (Sections 26-34).1.1.4 Test Method D for Bromide IonColorimetric, for concentrations from 40 to 6500 mg/L bromide (Sections35-44).1.2 Test Method A is intended for use
6、 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 Sa

It is the responsibility of the user of this standard to establish appro- priate sa
