摘要： Disclosed is a process and apparatus to analyze metal particles to determine their composition and to generate a sorting signal. The particles are exposed to a pulsed laser beam by which they are partly vaporized to form a plasma so that the particles are cleaned and the cleaned area is subsequently partially vaporized by a pulsed laser beam to form a plasma. The spectral lines of the plasma are inspected for an identification of the composition of the metal particles. The required inspection rate of 30 particles per second can readily be achieved or even exceeded if a defined narrow wavelength range or a defined wavelength is filtered from the total radiation that is emitted by the plasma and the intensities of the filtered partial radiations are related to each other to obtain ratios, which are compared with adjustable limiting values. A sorting signal is derived from the result of said comparison. The inspection rate can be improved in that the partial radiation is subjected to a comparison only for a defined interval of time.

摘要： A method for processing waste sulfuric acid which is contaminated with halides and has an acid content up to 40% which comprises subjecting the waste sulfuric acid to an electrodialysis in which the electric field causes the univalent halides to permeate through an anion exchange membrane and to be selectively removed while the divalent sulfate ions of the sulfuric acid are substantially retained, the sulfuric acid leaving the electrodialyzer being almost entirely free of halides. A corresponding apparatus is also provided.

摘要： A waste pickle which has been formed in the surface treatment of rolled stock consisting of steel and contains metal salts and acids and specifically contains nitric and hydrofluoric acids and nickel salts, chromium salts, and iron salts is subjected to an acid dialysis and a membrane electrolysis. To permit a recycling of free acids at a high rate and a recovering of the metals in a form in which they can directly be used in the melting process, the acid dialysis performed for a recovery of the free nitric acid and hydrofluoric acids is succeeded by a membrane electrolysis, in which the metals are recovered from the depleted effluent from the acid dialysis, which effluent has been depleted of free acid, and the enriched effluent from the acid dialysis, which enriched effluent has been enriched with free acids, and the effluent from the membrane electrolysis, which effluent has been depleted of metals, are subjected to an evaporation.
