Industrial production of gallium is mainly carried out by the electrolytic method using Bayer liquors of the aluminium industry. The major impediment to the effective recovery of gallium is known to be the presence of impurities (metallic and organic). Investigations on the effect of organics (aliphatic and aromatic) employing linear stripping voltammetry techniques on glassy carbon electrodes in alkaline gallate solutions revealed the inhibitive effect of these compounds on the electrodeposition of gallium and, hence, on gallium recovery from aluminate liquors.
