Notes:
Ferrous sample water will interfere with this test and can influence the readings. To determine
the ferrous iron concentration for correction purposes, repeat the test without adding PL Oxygen
Scavenger N°1. If the result is above 0.05 mg/l, subtract this value from the DEHA result.
During the reaction time, ensure the sample is kept in the dark.
Shake the liquid reagent thoroughly before adding the liquid to the vial.
