ISO 14403:2002 PDF

Scope: This International Standard specifies methods for the determination of cyanide in various types of water (such as ground, drinking, surface, leachate and waste water) with cyanide concentrations usually above 3 μg/1 expressed as cyanide ions. The CFA method is applicable to a mass concentration range from 10 μg/l to 100 μg/l. The range of application may be changed by varying the operation conditions. NOTE Seawater may be analyzed with changes in sensitivity and adaptation of the reagent and calibration solutions to the salinity of the samples.
