Bibliography
Defines methods for determining the cyanide in various types of water (such as ground, drinking, surface, leachate and waste water) with cyanide concentrations usually above 3 micro g/l expressed as cyanide ions. The CFA method applies to a mass concentration range from 10 micro g/l to 100 micro g/l. However, the range of application may be changed by varying the operation conditions.
