BS EN ISO 14403-1:2012

Water quality. Determination of total cyanide and free cyanide using flow analysis (FIA and CFA). Method using flow injection analysis (FIA) | Status: Confirmed, Current

1 Scope This part of ISO14403 specifies methods for the determination of cyanide in various types of water (such as ground, drinking, surface, leachate, and waste water) with cyanide concentrations 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 using a different injection volume. In this part of ISO14403, a suitable mass concentration range from 20 µg/l to 200 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.
