Description / Abstract:
This part of ISO 14403 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 from 2 μg/l to 500 μg/l expressed as cyanide ions in the
undiluted sample. The range of application can be changed by
varying the operation conditions, e.g. by diluting the original
sample or changing the pathlength of the flow cell.
In this method, a suitable mass concentration range from10 μg/l
to 100 μg/l is described.
Seawater can be analysed with possible changes in sensitivity
and adaptation of the reagent and calibration solutions to the
salinity of the samples.
