A Determination of the actual cyanide concentration in
   potassium cyanide stock solution
B Example for the determination of total cyanide and
   free cyanide by continuous flow analysis (CFA) with
   gas diffusion and amperometric detection
C Results of the interlaboratory trial for cyanide
   determination
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.
