ASTM D3866 - 12 Standard Test Methods for Silver in Water

Significance and Use

4.1 The principal adverse effect of silver in the body is cosmetic. It causes argyria, a permanent, blue-gray discoloration of the skin, eyes, and mucous membranes.

4.2 Relatively small quantities of silver are bactericidal or bacteriostatic and find limited use in both disinfection of swimming pool waters and point-of-use water filters.

1. Scope

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

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
