Method for the oxidative treatment of components comprised of or containing elementary silicon and/or substantially inorganic silicon compounds

摘要

In a method for the treatment of an object made of silicon or an inorganic, optionally organically modified, silicon compound, an oxidizing agent is prepared by electrolysis of an aqueous solution in an electrolysis device. The anode of the electrolysis device is a silicon electrode. The anode has an overvoltage for oxygen so that upon electrolysis of water the formation of hydrogen peroxide is preferred over that of oxygen. The aqueous solution used in electrolysis contains at least one reactive component or a constituent that is converted by electrolysis of the solution into a reactive component. The object to be treated is contacted with the freshly prepared oxidizing agent. The oxidizing agent is circulated and returned into the electrolysis device to be regenerated.
