    Today, reagent-based technologies for metal removal from water often fail to achieve the necessary purification efficiency for reuse and result in the accumulation of toxic sludge. This article aimed to test a regenerator for restoring the properties of etching solutions used in printed circuit boards, evaluate the performance of electrodes in depositing dense copper precipitates during etching solution regeneration, and explore the use of recovered copper in repair processes.
