The zeolite-modified carbon paste electrode

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1988
The electrochemical behavior of a Cu(II)-exchanged zeolite-modified electrode, constructed by incorporating the zeolite into the carbon powder + paraffin oil matrix used to manufacture a conventional carbon paste electrode, is investigated by cyclic voltammetric measurements.

Voltammetric determination of Celiptium with carbon paste and lipid-modified carbon paste electrodes [PDF]

Analytica Chimica Acta, 1990
Abstract The electrooxidation of the antitumour drug 2-methyl-9-hydroxyellipticinium (Celiptium) was investigated by cyclic, differential-pulse and adsorptive voltammetry at carbon paste (CPE) and lipid-modified carbon paste electrodes (LM-CPE). The influence of the paste composition, i.e., the ratio of graphite to binder, was studied in order to ...

Voltammetric study of glibenclamide at carbon paste and Sephadex-modified carbon paste electrodes

Analytical and Bioanalytical Chemistry, 2004
The oxidative behaviour of the antidiabetic agent glibenclamide on a bare carbon paste electrode (CPE) and a Sephadex-modified carbon paste electrode (SMCPE) was explored by cyclic and differential pulse voltammetry (DPV). The analysis procedure consisted of an open circuit accumulation step in stirred sample solution of Britton-Robinson buffer (0.04 ...

Voltammetric studies on carbon paste electrodes

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1984
ABstract The relative importance of the carbon and the pasting liquid on the properties of the carbon paste electrode was studied using cyclic potential sweep voltammetry. The effect on electrode capacity and kinetics for the systems hexacyanoferrate (II) and hydroquinone in phosphate buffer of pH 6.8 was compared.

Metal-dispersed carbon paste electrodes

Analytical Chemistry, 1992
The preparation of metal-dispersed carbon paste electrodes, based on mixing an organic binder with metalized graphite, is described. Such electrodes combine the efficient electrocatalytic activity of metal microparticles with the attractive properties of carbon paste matrices.

Comparative investigation on electrochemical behavior of hydroquinone at carbon ionic liquid electrode, ionic liquid modified carbon paste electrode and carbon paste electrode

Electrochimica Acta, 2007
Ionic liquid, 1-heptyl-3-methylimidazolium hexafluorophosphate (HMIMPF6), has been used to fabricate two new electrodes, carbon ionic liquid electrode (CILE) and ionic liquid modified carbon paste electrode (IL/CPE), using graphite powder mixed with HMIMPF6 or the mixture of HMIMPF6/paraffin liquid as the binder, respectively.

Chemically modified carbon paste and carbon composite electrodes

Electroanalysis, 1989
AbstractCarbon paste electrodes and composite carbon electrodes modified by 20% silica gel (30 μm) within the electrode material exhibit many properties typical of a strand of carbon fiber microelectrodes in voltammetric measurements. Charged and uncharged species were studied on these electrodes; phenol, ferricyanide, and potassium ethylxanthogenate ...

Adsorptive stripping behaviour of mitoxantrone on carbon paste electrodes

Talanta, 1993
The electrooxidation of mitoxantrone (MXT) on carbon paste electrodes was studied using voltammetric techniques in adsorption conditions. The analyte was accumulated at the working electrode (a carbon paste electrode) under precisely controlled mass-transport conditions and stripped electrochemically in the same solution.

Voltammetric determination of pyridoxine by use of a carbon paste electrode

The Analyst, 1975
The oxidation of pyridoxine and related compounds in ammonia buffer solutions is described and a fast and simple method for the determination of pyridoxine in pharmaceutical preparations is given. The only interferences are from ascorbic acid and iron(II), both of which can be removed by ion-exchange chromatography.
