The process of Co2+ ion extraction from sulphuric acid solutions by bulk liquid membranes, containing di(2-ethylhexyl)phosphoric acid and tri-n-octylamine, accompanied with cobalt electrodeposition from diluted solutions of some acids is studied at galvanostatic electrodialysis. The effects of the current density as well as of composition of the liquid membrane and aqueous solutions on the rate of cobalt(II) transport and electrodeposition are determined. It is demonstrated that a practically complete removal of Co(II) from the feed solution containing 0.01 M CoSO4 is achieved during 0.5 – 3.0 h of electrodialysis. Maximum stripping degree of 77% and electrodeposition degree of 45% are obtained under optimal conditions. Sound adherent cobalt coatings have been deposited on platinum and copper cathodes.
