摘要
Method and apparatus for regenerating etching solutions obtained by chemically 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.
