This International Standard specifies flow injection analysis (FIA) and continuous flow analysis (CFA) methods for the determination of chromium(VI) in various types of water. The method applies to the following mass concentration ranges. FIA: 20 ug/l to 200 ug/l and 200 ug/l to 2 000 ug/l for surface water,leachates and waste water. CFA: 2 ug/l to 20 ug/l and 20 ug/l to 200 ug/l for drinking water, ground water, surface water, leachates and waste water. The range of application may be changed by varying the operating conditions. Seawater may be analysed by these methods with changes in sensitivity and after adaptation of the reagent and calibration solutions to the salinity of the samples.
