Organization: ASTM International
Publication Date: 1 September 2012
Status: inactive
Page Count: 10
ICS Code (Examination of water for chemical substances): 13.060.50
significance And Use:

4.1 Copper is found in naturally occurring minerals principally as a sulfide, oxide, or carbonate. It makes up approximately 0.01 % of the earth's crust and is obtained commercially from... View More

scope:

1.1 These test methods cover the determination of copper in water by atomic absorption spectrophotometry. Three test methods are included as follows:

Test Method Concentration
Range

Sections
A-Atomic Absorption, Direct 0.05 to 5 mg/L  7-15
B-Atomic Absorption, Chelation-Extraction 50 to 500 μg/L 16-24
C-Atomic Absorption, Graphite Furnace 5 to 100 μg/L 25-33

1.2 Either dissolved or total recoverable copper may be determined. Determination of dissolved copper requires filtration through a 0.45-μm (No. 325) membrane filter at the time of collection. In-line membrane filtration is preferable.

1.3 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.

1.4 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 hazard statements, see Note 4, Note 6, Note 10, and Note 16.

1.5 Three former photometric test methods were discontinued. Refer to Appendix X1 for historical information.
