Bibliography

Colorimetric method for the determination of cyanide, as cyanogen chloride, applicable to cyanogen chloride concentrations of 0.02 to 15 mg/l.

This part of ISO 6703 specifies a method for the determination of cyanides, as cyanogen chloride (see clause 2) in water.

The method is applicable for the determination of cyanogen chloride concentrations in the range 0,02 to 15 mg/l.

The ions and compounds listed in the table, if present singly or in combination at concentrations above the specified limiting concentration, interfere with the method (the list is not exhaustive).

The presence of aldehydes, e.g. formaldehyde, may give lower cyanide values because of the formation of cyanohydrin.
