适用范围：This International Standard specifies flow injection analysis (FIA) and continuous flow analysis (CFA) methodsfor the determination of chromium(VI) in various types of water. The method applies to the following massconcentration ranges.FIA: 20 μg/I to 200 μg/I and 200 μg/I to 2 000 IJg/I for surface water, leachates and waste water.CFA: 2 μg/I to 20 μg/I and 20 μg/I to 200 μg/I 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 reagentand calibration solutions to the salinity of the samples.
