Cation Exchange Capacity (CEC)
nmsp.cals.cornell.edualuminum, iron and manganese. Cations such as zinc and copper are typically present in the soil in too low a concentration to occupy much of the CEC. Why do soils have a CEC? Soils have a CEC primarily because clay particles and organic matter in the soil tends to be negatively charged. New York soils have silicate clay minerals (clay minerals that

Manganese in rocks and minerals is unavailable to plants and becomes available very slowly as the minerals undergo chemical weath-ering. Most available manganese occurs as exchangeable manganese, manganese associated with organic matter, or vari-ous manganese oxides. Table 1 gives
Manganese in Drinking-water - World Health Organization
www.who.intManganese is used principally in the manufacture of iron and steel alloys and manganese compounds and as an ingredient in various products (IPCS, 1999; ATSDR, 2000). Manganese dioxide and other manganese compounds are used in products such as batteries, glass and fireworks. Potassium permanganate is used as an

40 Common Minerals and Their Uses
www.nma.orgManganese Ore is essential to iron and steel production. Also used in the making of manganese ferroalloys. Construction, machinery and transportation end uses account for most U.S. consumption of manganese. Manganese ore has not been produced in the U.S. since 1970. Major producers are South Africa, Australia, China, Gabon and Brazil. The U.S.
Decomposition of Hydrogen Peroxide by Various Catalysts
www.job-stiftung.deManganese dioxide is an example for a heterogeneous catalyst, i.e. the phase of the catalyst is different from that of the reaction mixture. The surface of solid manganese dioxide provides a particularly favorable environment to catalyze the decomposition, though the mechanism is not understood very well. For increasing the surface area
