As part of the programme on removal~recovery of toxic and valuable metals from dilute solutions, the removal of copper has been studied using a rotating cylinder electrode. Amongst the techniques like 111:idised bed electrode, porous flow through electrode etc. rotating cylinder electrode is simpler in lhat it offers a high mass transfer at low speeds &used by increased turbulence and is adaptable in a cascade system for continuous usage. Use of a rotating cylinder electrode with induced roughness caused by a wire mesh wrapped round the cathode has been investigated lor removal of copper from solutions of concentrations 100 ppm and less. The results obtained bring out the effects of current density, rotation rate, temperalure and surface roughness on the removal of copper. The benefits of increased surface roughness are shown as increased current efficiency and possibility of reducing the copper concentration down lo 1 ppm.
