1. Interference:
Iron (II) interferes at all concentrations: For the determination of iron (II)
concentration, the test is repeated without the addition of DEHA solution. Should the
concentration be over 20 μg/l, the displayed value will be deducted from the result of
the DEHA test result.
2. Substances that reduce Iron (III), interfere. Substances that complex iron strongly,
may also interfere.
