Abstract
A flow electrolytic cell is described which uses a vertical porous cathode composed of granulated coke. The cell is applied for the deposition of copper from diluted solutions, 10 −3-10 −2M, in the supporting electrolyte of 0.1 M Na 2SO 4 and 2% per weight H 2SO 4 in water. For the determination of concentration of copper ions in the effluent a radiometric method is applied using the radioactive isotope 64Cu. At the applied solution flow rates from 2 to 10 ml min −1, the coke electrode works efficiently, depositing on a single pass as much as 90% of copper ions present in solution.
