Standard Test Methods for Silver in Water

Standard Details

1.1 These test methods cover the atomic absorption determination of silver in water. Three test methods are given as follows:

	Concentration Range	Sections

Test Method A—Atomic Absorp- tion—Chelation-Extraction^A	1 to 10 μg/L	7 to 15
Test Method B—Atomic Absorp- tion—Direct	0.1 to 10 mg/L	16 to 24
Test Method C—Atomic Absorp- tion—Graphite Furnace	1 to 25 μg/L	25 to 33

^A Similar to that in Brown, E., Skougstad, M. W., and Fishman, M. J., “Methods for Collection and Analysis of Water Samples for Dissolved Minerals and Gases,” Techniques of Water-Resources Investigations of the U.S. Geological Survey, Book 5, Chapter A1, 1970, p. 46.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are mathematical conversions and may not be exact equivalents; therefore, each system shall be used independently of the other.

1.3 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. Specific precautionary statements are given in Note 4, Note 6, Note 11, and Note 15.
