Abstract:
1. Process for producing highly reactive reagents for purifying water or gas which is polluted by organic, inorganic or biological pollutants or constituents, comprising providing mixtures of various adsorber media, whose adsorption properties supplement one another in the mixtures characterized in that the mixtures of various adsorber mixture comprises as a main component a member selected from the group consisting of: (a) finely divided iron oxide and/or iron oxyhydroxide, the finely divided iron oxide and/or iron oxyhydroxide having a BET surface area of 50 to 500 m (b) manganese oxide and/or titanium oxides or (oxy)hydroxides, Fe(OH) (c) lime, iron exchanger, catalysts, and (d) copper compounds and/or zinc compounds and/or silver compounds whereby the main component is admixed with an aqueous suspension of iron oxide and/or iron oxyhydroxide, wherein the suspension, optionally after predrying, is subjected in the semisolid state to a mechanical shaping and subsequent drying, to achieve a solid state.
