✦ Synopsis

A method for the construction of carb'on paste electrodes (CPE) is described. Here ferrocene is used as the insoluble electroactive species, graphite powder as conductor and sulfuric acid as binder. The CPE thus prepared prevents ferrocenium ions from diffusing towards the bulk solutions. Voltammetric, chronolpotentiometric and chronoamperometric experiments performed with these CPEs show that the different preparation methods yield different electrochemical parameters for the ferrocene-ferrocenium system.

The electrochemical behaviour of PbO, at the solid state at a carbon paste electrode is studied. Several experiments with Pb,O, and PbO are also carried out in order to elucidate the electrochemical transformation of PbO,, occuring within +0.65 to -1.5 (see) range, into the carbon paste electrode wi
