ASTM D3869

Scope

1.1 These test methods 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 IonColorimetric, for concentrations from 0.2 to 2000 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 (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 applicability of regulatory limitations prior to use. For specific precautionary statements, see 20.2 and 39.2.
