10. Press TEST key.
Wait for a reaction period of 15 minutes (note 1).
After the reaction period is finished the measurement
starts automatically.
The result is shown in the display in mg/l Iron.
Notes:
1. Complexed iron may be measuredby increasing the development period until no further
colour development is seen. Very strongly complexed iron may not be included in the
measured iron. In this casethe complexing agent must be destroyed by oxidation with
acid/persulphatefollowed by neutralisation to pH 6–9.
Follow the procedure on page 166.
2. For total iron (suspendedand dissolved), boil sample with acid/persulphate. Neutralise
back to pH 6–9 making back up to original volume with distilled or deionisedwater.
Follow the procedure on page 166.
