CHEMetrics offers test kits employing the well-known Periodate reagent to deliver sensitivity and accuracy within two minutes or less. Based on CHEMetrics patented Self-Filling Reagent Ampoule technology. Premixed. Premeasured. Precise. Each kit contains 30 tests.

The Periodate Method

CHEMetrics' tests employ the periodate chemistry that measures soluble manganese compounds but does not differentiate the various valence states. Results are expressed as ppm (mg/l) Mn.

Permanganate (MnO4) develops approximately 25 % more colour with this reagent than other forms of manganese, causing a high bias. If the sample is known to contain manganese in the form of permanganate only, multiplying test results by 0.8 will improve the accuracy of the results.

Technical Data Sheet

Why Measure Manganese?

Manganese is a common component within industrial processes. It is used in the manufacture of batteries and as an alloying metal in the manufacture of steel and aluminium. 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.

Drinking water standards for Manganese are primarily set for aesthetic reasons. The National Prescribed Concentration or Value (PCV) for Manganese in drinking water supplies in the UK is 0.05 mg/l (50µg/l). The Specified Concentration or Value (SCV) for manganese in drinking water in Ireland is the same, as is the US National Secondary Drinking Water Regulations secondary standard. The USEPA's Lifetime Health Advisory value is 0.3 mg/l (300µg/l) in drinking water, below which adverse health effects are not expected.

What is Manganese?

Manganese is a brittle, silvery metal and transitional element that can act as an oxidising or a reducing agent depending on its valence state. It is most commonly found in mineral form as manganese dioxide (pyrolusite) and carbonate (rhodochrosite) and occurs naturally in soil, groundwater and surface water.

Surface and groundwaters rarely contain more than 1 mg/l of soluble or suspended manganese. Dark rock deposits of MnO2 can discolour water passing through it. Higher concentrations may indicate pollution from industrial discharges.

While trace amounts of manganese found in food sources are essential for human health, elevated levels of Manganese in drinking water are neurotoxic. Manganese in drinking water will impart a foul taste and discolour laundry and porcelain surfaces before it reaches toxic levels.

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.
