VISOCOLOR® ECO Manganese
Colorimetric determination of manganese
In alkaline solution manganese ions react with formaldoxime to form an orange-red complex.
Nickel interferes causing a yellow-green reaction colour.
(Reaction principle analogous to DIN 38406-E2)

Natural waters contain manganese in the divalent, soluble form as well as in colloidal tri- and tetravalent states. Valencies are interchanged by oxidation-reduction reactions taking place in the water. The test procedure determines all oxidation states of manganese.
