Standard Test Methods for Copper in Water
|Publication Date:||1 June 2017|
|ICS Code (Examination of water for chemical substances):||13.060.50|
These test methods cover the determination of copper in water by atomic absorption spectrophotometry. Section 34 on Quality Control pertains to these test methods. Three test methods are included as follows:
A-Atomic Absorption, Direct
B-Atomic Absorption, Chelation-Extraction
C-Atomic Absorption, Graphite Furnace
Either dissolved or total recoverable copper may be determined. Determination of dissolved copper requires filtration through a 0.45-μm (11.10) membrane filter at the time of collection. In-line membrane filtration is preferable.
The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversion to inch-pound units that are provided for information only and are not considered standard.
Three former photometric test methods were discontinued. Refer to Appendix X1 for historical information.
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 11.3, 11.9.1, 20.10, and 22.11.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
