MN VISOCOLOR® ECO test kit iron 2, 0.04-1.0 mg/l Fe
Description
VISOCOLOR® ECO Iron: Colorimetric determination of iron.
Features:
• Triazine method: iron(II) ions react with a triazine derivative to form a violet complex.
• Iron(III) ions are reduced and thus also determined.
• Natural waters as well as waste waters often contain some iron.
• It can be present as Fe(II) or Fe(III) ions if the pH value of the water is below 3 or if the water is free of oxygen.
• At higher pH values Fe(III) forms an insoluble oxyhydrate.
• Frequently the sample is in a transition state with finely dispersed iron oxides.
• In waste water and natural water containing humic acids iron is often present in the form of a complex salt.
• The VISOCOLOR® test kits only determine iron which is present in dissolved form as Fe2+ or Fe3+ ions.
• Iron complexes are not covered unless they are decomposed by oxidation with nitric acid and sulphuric acid.
