Abstract
The method is applicable to unalloyed coppers not containing elements providing insoluble residues in the electrolytic solution. Annex A gives test portions of test sample and of copper precipitate. Annex B describes a spectrophotometric method for the determination of residual copper in the electrolytic solution after deposition of copper on the cathode.
