Organization: ASTM
Publication Date: 15 February 2006
Status: inactive
Page Count: 20
ICS Code (Examination of water for chemical substances): 13.060.50
scope:

These test methods cover the determination of cyanides in water. The following test methods are included:

Cyanogen halides may be determined separately.

NOTE 1-Cyanogen chloride is the most common of the cyanogen halide complexes as it is a reaction product and is usually present when chlorinating cyanide-containing industrial waste water. For the presence or absence of CNCl, the spot test method given in Annex A1 can be used.

These test methods do not distinguish between cyanide ions and metallocyanide compounds and complexes. Furthermore, they do not detect the cyanates.

NOTE 2-The cyanate complexes are decomposed when the sample is acidified in the distillation procedure.

The cyanide in cyanocomplexes of gold, platinum, cobalt and some other transition metals is not completely recovered by these test methods.

Cyanide from only a few organic cyanides are recovered, and those only to a minor extent.

Part or all of these test methods have been used successfully with reagent water and various waste waters. It is the user's responsibility to assure the validity of the test method for the water matrix being tested.

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 hazard statements are given in sections 5.1, 8.8, 8.18, 9, 11.2, and 16.1.9.
