MN VISOCOLOR® HE test kit manganese, 0,03 – 0,50 mg/l Mn

VISOCOLOR® HE 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) • Type: high sensitive test kit • Range: 0.0 · 0.03 · 0.06 · 0.10 · 0.15 · 0.20 · 0.25 · 0.30 · 0.40 · 0.50 mg/l Mn • Sufficient for: 100 determinations • Shelf life at least: 18 months • Sea water suitability: yes, but depending on the composition of the sea water • Detectable with PF-11: no • 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.
