Standard Test Methods for CYANIDES IN WATER

Organization: ASTM
Publication Date: 30 January 1981
Status: inactive
Page Count: 22
ICS Code (Examination of water for chemical substances): 13.060.50
scope:

These methods cover the determination of cyanides in water, waste water, and saline water. However, the analyst should recognize that the reported precision and accuracy statements may not apply to waters of different matrices.

These methods do not distinguish between cyanide ions and metallocyanide compounds and complexes. Furthermore, they do not detect the cyanates (Note 1), or the cyanogen halides, with the exception of chloride (Note 2), which may be determined separately.

NOTE 1-The cyanate complexes are decomposed when the sample is acidified in the distillation procedure.

NOTE 2-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.

The cyanide in some cyano complexes of some transition metals; that is, cobalt, gold, and platinum is not completely determined.

Only a few organo-cyanide complexes are recovered, and those only to a minor extent.
