  • Method of regeneration of spent etching solutions
    Patent number: 4107011
    Abstract: The present invention is concerned with a method of regeneration of spent etching solutions containing cupric chloride and a metal chloride: cuprous chloride or ferrous chloride. These solutions are subjected to electrolysis with copper being reduced at the cathode and the metal chloride being oxidized at the anode. At the same time, chlorine is liberated at the anode, which is used for additional oxidation of the chloride of a metal.The proposed method permits effective regeneration of etching solutions without polluting the environment.
