  • Publication number: 20240133067
    Abstract: Disclosed is a method of removing lead materials from an anode for manufacturing copper foil to regenerate the anode. The method includes cleaning solution preparation, anode cleaning and anode washing. The cleaning solution preparation includes preparing a cleaning solution containing an aqueous solution of EDTA and citric acid. The cleaning solution used to perform the anode cleaning has a pH of 7 to 9 and a temperature of 20 to 50° C. The anode cleaning includes cleaning the anode by immersing the anode including the lead materials attached to the surface thereof in the cleaning solution to perform EDTA-Pb chelation. As a result, the transfer of the lead materials from the anode to the cleaning solution means substantial removal of the lead materials from the anode. The anode, from which the lead materials have been removed, is washed using a high-pressure washer.
