What is Manganese?
Manganese is a mineral that occurs naturally in soil, ground water, and surface water. Concentration is usually less than 1 mg/L of soluble or suspended manganese in the natural environment. Higher concentrations may indicate pollution from industrial discharges. Manganese can act as an oxidizing or reducing agent depending on its valence state. This property makes it a common component within industrial processes. It is frequently used in the manufacturing of batteries and as an alloying metal in the manufacture of aluminum and steel.
Why Test for Manganese?
While trace amounts of manganese are essential for human health, high levels can cause harm. The US EPA has developed a Health Advisory Level of 0.3 mg/L in drinking water. Even at lower concentrations, manganese causes many aesthetic problems. Manganese can cause black flecks of manganese dioxide (MnO2) in water, discoloration to laundry and porcelain surfaces, and a bitter or metallic taste in water. For these reasons, drinking water testing for manganese is necessary, and the National Secondary Drinking Water Standard for manganese is 0.05 mg/L.
Industrial facilities will want to measure their manganese discharge as it is a growing concern for communities. Manganese in combination with iron can clog pipes and foul ion exchange systems, reducing efficiency if not properly controlled. Soluble forms of manganese (and iron) may be controlled by aeration by oxidization to insoluble precipitates which can then be removed by clarification or filtration.
About Our Test Kits
CHEMetrics visual manganese water test kits feature CHEMets® self-filling ampoules that contain pre-measured reagent for a single test. Simply snap the ampoule directly in a sample to draw in the correct volume of sample and then compare to the supplied color standards to find the concentration.
CHEMetrics instrumental manganese water test kits feature Vacu-vials® ampoule technology. Vacu-vials ampoules utilize the same self-filling technology as CHEMets ampoules, but the vials have a 13mm diameter, so they are compatible with most photometers or spectrophotometers.
