    摘要： The use of alkali metal, alkaline earth metal, ammonium and substituted ammonium salts of alkyl and alkanol sulfonic acids as additives in various types of electroplating baths (e.g., sulfate, sulfonic acid, fluoroborate, and halide baths) has a number of unexpected benefits including wider useful current density range, improved appearance and in the case of tin improved oxidative stability.

    摘要： The present application relates to a sterilizing and environment-friendly composite plating layer, a preparation method thereof and a sterilizing and environment-friendly product. The sterilizing and environment-friendly composite plating layer includes: a semi-bright nickel layer, a high-sulfur nickel layer and an environment-friendly white chromium composite sterilizing layer; the semi-bright nickel layer is adapted to be positioned on a substrate having a sterilizing requirement; the high-sulfur nickel layer is disposed on the surface of a side of the semi-bright nickel layer away from the substrate; the environment-friendly white chromium composite sterilizing layer is disposed on the surface of a side of the high-sulfur nickel layer away from the substrate; the environment-friendly white chromium composite sterilizing layer has a nano-needle structure and is formed by a composite raw material containing sterilizing ammonium salt, and the concentration of the sterilizing ammonium salt in the composite raw material is 50-100 g/L. The sterilizing and environment-friendly composite plating layer and the sterilizing and environment-friendly product of the present application can be prepared directly by an electroplating method, and can have good broad-spectrum sterilizing effect without spraying antibacterial materials containing nano Ag + , Cu 2+ , and the sterilizing effect can be directly displayed.

    摘要： Raw lead to be refined is leached in a leach apparatus with a leach solution containing fluoro compounds, in particular ferric fluorotitanate. During the leaching step, lead is dissolved, with ferric fluoro compounds being reduced to ferrous fluoro compounds. The leaching solution resulting from the leaching step is sent to the cathodic compartment of a diaphragm cell in which lead is deposited on a cathode, in compact, highly pure form. The solution that is depleted of lead is sent to the anodic compartment in which a suitable anode oxidizes the ferrous fluoro compound to ferric fluoro compounds that can be recycled to the leaching step. A process for electrorefining of lead from a lead source, e.g. a lead bullion, comprises electrolyzing an anode (lead bullion) or an electrolyte containing a fluorotitanate compound and depositing refined lead on a cathode.
