Abstract: A method for denitrification of water, in which the water to be denitrified is made to flow over a porous carrier which comprises a transition metal, preferably palladium, used in an amount between 0.01 and 5% by weight on the carrier and on which denitrifying bacterial strains capable of surviving in the presence of hydrogen are made to adhere, and in which hydrogen is used as a reducing agent and the pH of the reaction is adjusted to values of 4.5 to 7.8 preferably by using carbon dioxide.

Abstract: Oxidation catalysts usable in particular in the full oxidation to CO2 and H2O of volatile organic compounds such as hydrocarbons comprising mixed oxides of copper, manganese and one or more rare-earth metals, wherein the metals can assume multiple valency states, having a percentage composition by weight, expressed as CuO, MnO and rare-earth oxides, in which the metal has the minimum value of 8-50%, 10-75% and 2-15%. The oxides are supported on inert porous inorganic oxides.

Abstract: Highly pure iron oxides are prepared by reaction of metallic iron, in the form of microspheroidal particles or of scraps or cuttings, with an agitated aqueous solution of a mono- or polycarboxylic acid with a pKa of 0.5 to 6 relative to the first carboxyl and capable of decomposing, by heating in air at 200 to 350null C., to carbon dioxide and water, using 0.03 to 1.5 moles of acid per g-atoms of iron, a water/iron weight ration of 1 to 20, and by oxidation of the ferrous carboxilate to ferric salt, with an agent selected from oxygen, mixtures containing oxygen, hydrogen peroxide, organic peroxides and hydroperoxides.
