Abstract: Ni(Ⅱ) ion is complexed by poly-8-hydroxyquinoline, poly-0-aminophenol, poly-0-diaminobenzene and polyaniline as ligands. The voltammograms for the polymer-Ni (Ⅱ) film electrode show well defined reduction and oxidation peaks. They have similar electrochemical properties. Poly-8-hydroxyquinoline film, poly-0-aminophenol film and poly-0-diaminobenzene film can be used to exchange Ni (Ⅱ) with H~+ ion and to separate Ni(Ⅱ), Co (Ⅱ) and Fe(Ⅱ) ions.

Key words: Film electrode, Voltammograms, Electrochemical polymerization, 8-hydroxyquinoline, Aminophenol, Diaminobenzene, Aniline
