scope:
This standard specifies a method for determination of the chromium content of water by means of atomic absorption spectrophotometry (graphite furnace technique). It applies to aqueous sollutions that have to be clear or that have to be centrifuged or filtered. The detection limit depends on the equipment used, generally speaking chromium contents starting at 0.5 µ g/l can be determined. For chromium contents higher than 100 µ g/l the flame technique is recommended.
