Mercury nucleation on glassy carbon electrodes

Analytica Chimica Acta, 1997
Abstract The amount of mercury, deposited on a glassy carbon electrode at various potentials during the first 200 ms of electrolysis, has been determined by constant current coulometric stripping potentiometry. Eight microliter samples, containing approximately 4 M chloride, were placed on top of a combined glassy carbon, Ag counter and Ag AgCl

Electrochemical studies on glassy carbon electrodes

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1973
Summary Rate constant measurements for charge transfer processes at various electrodes show the general sequence k s (Pt)> k s (glassy carbon)> k s (wax-impregnated graphite) > k s (carbon paste). Maximum rates on glassy carbon electrodes have been observed after treatment with chromic acid, except for the reduction of iodate ion, where ...

Electrosorption of quercetin on glassy carbon electrode

Journal of Electroanalytical Chemistry, 2011
Abstract The present paper reports a concise study on the mechanism of electrosorption of quercetin (3,3′,4′,5,7-pentahydroxyflavone) molecule on glassy carbon (GC) electrode surface in 0.1 M sodium acetate–acetic acid buffer, in 90% methanol solution.

Adsorption of Simazine on a Glassy Carbon Electrode

Bulletin of the Chemical Society of Japan, 2010
Abstract Differential capacity–potential curves have been measured for the s-triazine herbicide simazine at different concentrations. The decrease in capacity was independent of the applied potential, so the adsorption is also independent of the potential. The adsorption follows a Langmuir type isotherm.

Electrochemistry of ABTS at Glassy Carbon Electrodes

Chinese Journal of Chemical Physics, 2011
The electrochemical and the mass transport behavior of ABTS2−/ABTS.− (2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonate)) redox couple at glassy carbon electrode (GCE) in phosphate buffer solution (PBS, pH=4.4) is studied in detail by cyclic voltammetry combined with rotating disk electrode system.

Reduction of Carbon Dioxide on Modified Glassy Carbon Electrodes

Journal of The Electrochemical Society, 1999
Carbon dioxide in the atmosphere gives an important contribution to environmental pollution due to the progressive increase of its production everywhere from many sources. It is believed now that the capacity of the biosphere, due to absorption and transformation of CO{sub 2}, has been considerably exceeded and many attempts to overcome this problem by

Surface preparation of glassy carbon electrodes

Analytica Chimica Acta, 1988
Abstract Recent work on glassy carbon electrodes for various applications is reviewed. Activation of glassy carbon electrodes by different types of polishing, heat treatment, and electrochemical methods yields enhanced rates of electron transfer.
