Abstract
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.
