Abstract: Spontaneous and sustained reduction and accumulation of elemental gold from chloroauric acid solution by electroactive polyaniline in the leucoemeraldine and emeraldine oxidation states have been demonstrated and explained. A typical polyaniline film can accumulate more than five times its own weight of gold ([Au]/monomer mole ratio > 2) before the reduction rate is substantially retarded by the loss of active surface area due to gold coverage. © 1993.
