摘要： Systems and methods for the recovery of noble metal from noble-metal-containing material are generally described. Certain embodiments related to systems and methods in which an electric current is transported between an electrode and the noble metal of a noble-metal-containing material to dissolve at least a portion of the noble metal from the noble-metal-containing material. The dissolved noble metal can subsequently be precipitated out of solution and recovered, according to certain embodiments. Noble metals can be recovered from any suitable noble-metal-containing material, including plated and/or filled scrap materials and/or other materials.

摘要： A method of producing ammonium persulfate by electrolyzing ammonium sulfate is characterized in that an ammonium sulfate aqueous solution is supplied as an anode-side feedstock, a solution containing less than 1.0 mol of acid-derived acid dissociable hydrogen ions per 1.0 mol of amount of charge transfer is supplied as a cathode-side feedstock, and electrolysis is performed to produce ammonium persulfate on the anode side and at least ammonia on the cathode side. Since ammonium sulfate not dependent upon the ammonium sulfate produced within the system can be used as a main feedstock, the method is industrially advantageous and, further, because of an electrolytic method, the method enables the coproduction not only of ammonium persulfate but also of valuable materials such as ammonia and hydrogen and, furthermore, enables the production of ammonium persulfate at a high current efficiency.

摘要： An industrially useful peroxo-carbonate is electrolytically produced using, as a raw material, carbon dioxide that is inexpensive and easily available. A process of producing a peroxo-carbonate, includes feeding a carbon dioxide gas into an electrolytic cell having a gas diffusion anode and a cathode, or feeding a liquid having a carbon dioxide gas dissolved therein into an electrolytic cell having an anode and a cathode, and electrolytically converting the carbon dioxide gas into a peroxo-carbonate. By properly setting up electrolytic conditions such as electrodes, a useful peroxo-carbonate can be produced with high current efficiency using inexpensive carbon dioxide as the raw material.

摘要： A method and apparatus for the generation and collection of an aqueous peracid solution at the cathode of a PEM electrolyzer. The electrochemical process introduces carboxylic acid (such as distilled table vinegar, lactic acid, citric acid or combinations) to the anode and a source of oxygen to the cathode. The PEM electrolyzer has a gas diffusion cathode having a cathodic electrocatalyst that is capable of hydrogen peroxide generation. The peracid solution is generated at the gas diffusion cathode and the solution is very pure and may be used for disinfecting or sterilizing various items or solutions. In a second embodiment, the carboxylic acid may be provided directly to the cathode, such as in the form of an acid vapor.
