carbon fiber electrodes (residual graphite oxide fibers) electrochemically oxidized and partially rereduced in concentrated h//2so//4 have excellent cation-exchanging properties. chemically modified carbon fiber electrodes have been prepared by na** $plus$ -exchange of residual graphite oxide fibers and subsequent action of chlorocompounds in methanolic solutions (the williamson reaction) the attachment of the various reagents on to the carbon fibers is reflected through the corresponding cyclic voltammograms obtained in aqueous buffer solutions. when modified with iron phthalocyanine, carbon fiber electrodes show a significant catalytic effect on the electrochemical reduction of oxygen in aqueous and methanolic solutions. 14 refs
