Apparatus for carrying out the method and a method for regenerating an iron-containing etching solution used in etching or pickling copper or copper alloy

摘要

You express concerning the device in order to execute the method and its method in order to play back the iron content etchant which is used the occasion where etching or pikuringu it does the copper or copper alloy. The aforementioned method, has been closed airtight etchant, from the etching system, or expedient in order to remove the copper which was precipitated the anode hood (8) process and the cathode which are moved to the electrolytic cell which it possesses (1), consists of the inactive anode (2) the electrolytic cell which, due to electrolysis from the aforementioned cathode (3) and collects the copper which is removed and the description above expedient in order to impress electric potential in the copper which is removed includes and becomes (4), the aforementioned electrolytic cell does not have the ion exchange membrane or the diaphragm.
