摘要： Method and apparatus for regenerating etching solutions obtained by chemily processing metallic surfaces, which solutions contain cupric chloride and/or ferric chloride. The apparatus includes between the anode and the cathode a diaphragm or an ion exchange membrane. The etching solution is passed through the electrolysis cell for anodic oxidation of the cuprous and/or ferrous ions obtained by etching of the metallic surface of a workpiece. An effective quantity of activated pulverous carbon particles is suspended at least in the anode compartment of the electrolysis cell, which cell is in communication with an etching chamber in such a way so as to allow circulating flow of solution.

摘要： A plate or hollow cylinder of coarsely porous graphite is coated with a layer of finely porous activated carbon that has previously been heat-treated. The fine layer is impregnated with a catalyst either before or after application to the graphite body. A gas is caused to flow through the graphite body and out through the finely porous layer containing the catalyst, to react with substances in a solution in which the carrier body is immersed. For oxidation, air can be used, and for reduction, hydrogen. In this manner, sulfite can be oxidized or chromate reduced and hydrogen gas can also be used to precipitate platinum, rhodium, copper and other metals from solution. Electro-chemical activation or regeneration of the catalyst is possible by applying a potential to the carrier body. The reaction can be carried on in solutions in which solids are suspended without clogging the catalyst.

摘要： Reducible pollutants can be detoxified by reduction and metals can be recred by reduction of the corresponding metal ions by bringing into contact a catalyst with the solution which is suitable for the electrochemical reduction of the ions in question, and mixing into the solution (or bubbling therethrough in the case of a gas) a reducing agent that has a redox potential in the redox system of the reducing agent and its oxidation product that is more negative than the redox potential of the substance to be reduced and its reduction product. The catalyst is a material that is suitable for use as an anode material at which hydrogen can be oxidized in a fuel cell. Such catalysts include finely divided platinum, activated carbon coated with platinum, tungsten carbide and activated carbon coated with tungsten carbide, particularly. Hydrogen is a good reducing agent for the purpose.

摘要： An electrolytic cell which between the anode and cathode includes a diaphm dividing the electrolytic cell into two chambers. In one of these chambers there is provided an electrolyte which contains the suspension of electrically conductive bodies. The apparatus includes a treatment chamber for workpieces to be arranged in a contact-free manner with regard to the cathode and anode. A conveying line for the electrolyte containing the electrically conductive bodies extends between on one hand that chamber of the electrolytic cell in which the electrode charging the electrically conductive bodies is arranged, and on the other hand the treatment chamber. One portion of said conveying line outside the electrolytic cell includes a porous wall which is permeable for the electrolyte but retains electrically conductive bodies. The annular chamber formed by a surrounding outer pipe and porous wall which surrounds the conveying line communicates with the chamber containing the counter-electrode in the electrolytic cell for exchanging electrolyte.

摘要： Ammoniacal etching solution containing metal ions as the result of etching is withdrawn from an etching bath and while part of it goes to an electrolysis cell for removal of metal ion, the remainder goes back to the etching bath through a liquid jet pump in which it serves as the working liquid, while the pump sucks in from the electrolysis cell the anodically evolved oxygen. The thorough mixing of the oxygen into the etching solution performed by the pump results in oxidation so rapid that in many cases it becomes unnecessary to suspend catalyst particles in the electrolyte to accelerate the oxidative regeneration of the etching solution. Where use of such particles is still desired, the solution drawn from the etching bath goes through a cylindrical filter unit from which a filtrate is drawn off laterally for the electrolysis cell, while the remainder of the input goes to the jet pump. Controls are provided for using the electrolysis cell only when the metal ion concentration is above a predetermined value, for adding ammonia to the oxygen line in order to maintain a particular value of pH and for controlling the temperature of the electrolyte in the electrolysis cell in order that a desired quantity of water can be condensed from the oxygen line for use in rinsing the work pieces after they are taken out of the etching bath.

摘要： In a process for reduction or oxidation of materials in aqueous solution byassing a reagent gas through a finely porous catalyst layer into the solution, bodies of electrically conducting material which in the aggregate have a large surface are brought into electrically conducting connection with the catalyst layer on its side facing the solution in order to increase the rate of conversion of the dissolved material. The conducting bodies are distributed in the solution at least in the region of the catalyst layer and increase the effective surface for the conversion of the dissolved material. The invention is particularly useful in connection with catalyst layers provided with an electrically conducting protective cover through which gas and solution may pass on the side of the catalyst layer facing the solution as disclosed in a related application of the same inventors Ser.

摘要： In addition to catalyzing the reoxidization of spent alkaline etching age the suspension of activated carbon powder in the etching solution also increases the speed of etching when the etching solution is recirculated in the etching of printed circuit boards. The ammonium sulfate etching solution is set to a pH of about 9 by the addition of ammonia gas. In the recirculation of the etching solution, a part of the solution can be freed by filtration from suspended carbon particles and passed through the cathode and anode chambers of an electrolysis cell for the recovery of the etched metal by deposition on the cathode. The activated carbon powder for this purpose is calcined before use, at a temperature of between 900.degree. and 1200.degree. C. in vacuum or in an atmosphere that is inert, reducing, or only slightly oxidizing as in the case of an atmosphere containing carbon dioxide, water vapor or both, in a concentration that does not appreciably oxidize the carbon particles.
