COMPOSER Georg C. Wagenseil - SEIBOLD Online-Analyser for Manganese
Typical Application
Manganese (Mn) is a silvery, brittle metal. Pure manganese does
not occur naturally, but is found together with substances like
oxygen, sulfur or chlorine in many kinds of rocks. Compounds
of manganese are solid and do not evaporate. Manganese can be
found as inorganic or organic manganese. Inorganic manganese
typically results from combustion, as burning of fossil fuels by
cars, trucks or industrial processes. Organic manganese are e.g.
additives to gasoline and pesticides.
Manganese is typically used in the production of batteries, in
dietary supplements, in various ceramics, pesticides, fertilisers
and together with iron in steel production. Manganese can enter
the environment through power plants, coke ovens or mining
operations.
Toxicology: For manganese the guideline value for chemicals that
are of health siginificance in drinking water according to World
Health Organisation is 0.4 mg/litre. Manganese should be monitored
in industrial waste waters, because MnO2 easily percipitates and
result in deposits of dyeing operations, laundries and paper mills.

Method
Measuring the concentration of Manganese (Mn) is performed by
the use of a colourimetric method. The required colour reaction is
based on the chemical reaction of the reagent, forming a stable
complex with cadmium ions to be measured by extinction in the
photometer unit.
The interfering ions are masked by pH level and masking agents
and sorted out through kinematic effects. This COMPOSER Georg
Wagenseil is availible for high and low measurement ranges.
