โœฆ Synopsis

AbstmceThe Fe(CN)i-'*-charge-transfer reaction was studied with anion-exchange polymercoated electrodes. SOi-and CIO; were mainly used as the anions of the background electrolyte. The electrochemical results are correlated with the equilibrium distribution of the ions between the electrolyte and the coating. Since the considered anions are ir-active their concentration in the iilm could be determined by ir-reflection-absorption spectroscopy, after the coated electrodes had been withdrawn from the electrolyte. The strona influence of the films' ion-exchange selectivity on the electrode behaviour is demo&rated.

Dodecylsulphate was incorporated into a polypyrrole matrix during anodic polymerization of pyrrole. The concentration was adjusted such that in the oxidized film about one half of the polypyrrole cationic groups was charge compensated by the sulphate groups from the incorporated dodecylsulphate, the

Some pH-responsive glass electrodes have been characterised with respect to gel layer thickness, durability and ion exchange capacity. Glasses with a low durability exhibited a thick gel layer and a high ion exchange capacity in comparison with high durability glasses. The electrochemical properties
