摘要： The electrolytic process for dissolving platinum, platinum metal impurities and/or platinum metal alloys, in particular with contents of Rh, Pd, Ir, Au and Ag, in 6 to 8N aqueous hydrochloric acid is characterized by a dissolution process that takes place in an electrolysis cell subdivided by a cation exchanger membrane into an anode and cathode compartment containing anode and cathode respectively, and, if appropriate, in the presence of platinum metal salts or platinum metal acids, at temperatures between 50.degree. and 110.degree. C., under potentiostatic or voltage-controlled conditions in the range of 2.5 V to 8 V and under a current density of 0.3 to 7.0 A/dm.sup.2. The potential across the anode and the cathode is controlled so that chlorine gas is generated and the anode is contacted with the aqueous hydrochloric acid solution and the chlorine gas in impulse-form.

摘要： A process for electrolytic production of fine-grained, single-phase, metallic alloy powders, especially powders of intermetallic compounds as well as noble metal alloy powders, is described in which powdery metallic precipitates are galvanically produced on the cathode from an electrolytic precipitating bath known in the art, which contains in solution the metals to be precipitated, under electrolysis conditions causing a powder precipitation known in the art. For the production of alloy powders with defined properties, it is determined, first in preliminary tests by gradual increase of the cathode potential with otherwise constant process parameters, the minimum cathode potential at which single-phase alloy powders result and then the powder precipitation is potentiostatically performed in a cathode potential at or above the minimum for the single-phase alloy precipitation.

摘要： The invention relates to the production and use of novel bioactive devices and metallic coatings for example for sterilizing, disinfecting, and decontaminating water or aqueous solutions. The known oligodynamic effect of silver for reducing the amount of germs is thereby improved and increased by combining silver with ruthenium and a vitamin or derivative thereof. The novel properties of these bioactive metal surfaces lead to faster and more efficient killing of microorganisms. Simultaneously, these novel bioactive metal surfaces prevent infestation by microorganisms and attachment or permanent deposition of problematic biomolecules such as for example DNA, RNA, or proteins. A self-cleaning surface is thus obtained, which very quickly and efficiently and over extended periods of time sterilizes water and aqueous solutions when they come in contact with said surface.
