Catalytic effects of high Mn(IV) concentrations on Mn(II) oxidation

Abstract

Manganese is one of the common constituents of impounded water and of many well waters. In public supplies, it causes difficulties such as staining of clothes, "black" residues on plumbing fixtures and incrustation of mains. in industrial supplies, it causes severe economic losses through discoloration of products, specks in finished paper,textile, food and beverage products, and reduction of pipeline carrying capacities. Manganese is not known to cause any health problems, and the above conditions are limited to existence of manganese content by 0.05 mg/l in drinking waters, and by 0.1 mg/l or less in industrial waters.
