摘要：

Cu was electrochem. removed from an aq. soln. of CuSO4 (1.0 g Cu2+/L) in a cell with 6 bulk cathodes made of graphite cubes 10x10x10 mm, graphite rollers diam. 5 mm, height 5 mm and irregular coke chunks 3-5 mm in size. The final concn. was decreased down to 1-3 mg Cu2+/L when coke chunks were used as the cathode. A new concept of using removable cathodes shell decrease the Cu concn. down to below 0.2 mg Cu2+/L.
