| Summary: | We report the voltammetry of basal plane pyrolytic graphite electrodes partially covered with immobilised microdroplets of n-butylferrocene and immersed in various aqueous electrolyte solutions. Oxidation of the redox-active oil droplets to form the n-butylferrocinium cation takes place with the expulsion of the cation from the oil phase. The dissolution process is accompanied by the formation of ion pairs between the n-butylferrocinium cation and the counter anion in the aqueous solution; adsorption of the parent compound on the solid electrode surface is also observed. © 2002 Elsevier Science B.V.
