Adsorption of some quinone derivatives at electrochemically activated glassy carbon electrodes

open access: yesJournal of Electroanalytical Chemistry, 2004
The adsorption interactions between different quinone derivatives at electrochemically activated glassy carbon have been studied. Experimental results demonstrated that there were two different types of adsorption sites present at the activated electrode

Preconcentration and Electroanalysis of Copper Species at Electrochemically Activated Glassy Carbon Electrodes [PDF]

open access: yesElectroanalysis, 1998
Electrochemically activated glassy carbon electrodes were applied to the preconcentration and electroanalysis of metal species. Activated glassy carbon electrodes were obtained by potentiostatic oxidation at +2.0V in 0.5 M sulfuric acid.

Electrochemical reduction of metronidazole at activated glassy carbon electrode and its determination in pharmaceutical dosage forms

open access: yesJournal of Pharmaceutical and Biomedical Analysis, 1998
A voltammetric method has been developed for the determination of metronidazole in dosage forms. The method is based on the electrochemical reduction of the drug at a glassy carbon electrode activated by applying a new pretreatment.
