Determination of DEHA
|
|
|
Measurement of the reduction properties of DEHA for iron(III) ions and determination of the iron(II) ions formed. Strictly observe the temperature and reaction time since they strongly influence the colour intensity.
Iron(II) ions interfere. This error can be taken into account by a modified test procedure.
