N-propylpyridinium chloride silsesquioxane polymer film on graphite: electrochemical study of a hexacyanoferrate (II) ion immobilized electrode for oxidation of ascorbic acid
A well polished graphite surface was coated with a thin film of N-propylpyridinium chloride silsesquioxane polymer. On to the strongly graphite-adhered polymer film the electroactive species [Fe(CN)6]4- was adsorbed by means of an ion exchange reaction. The resulting electrode (graph/SiPy+)4[Fe(CN)6...
