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
Iron and Manganese Removal - MRWA
www.mrwa.comIron and manganese in water can also be oxidized by chlorine, converting to ferric hydroxide and manganese dioxide. The precipitated material can then be removed by filtration. The higher the amount of chlorine fed, the more rapid the reaction. Most treatment plants use 1 – 2 parts of chlorine to 1 part of iron to achieve oxidation.

www.who.intmanganese(II). When chlorine dioxide reacts with aqueous contami-nants, it is usually reduced to chlorite ion. The corresponding electron transfer reactions are comparable to those occurring when singlet oxygen acts as an oxidant (Tratnyek & Hoigne, 1994). Bromide (in the absence of sunlight) is not oxidized by chlorine dioxide.
