Adsorptive square-wave voltammetry of quasi-reversible electrode processes with a coupled catalytic chemical reaction
(Springer, 2016-12-09)
There are several strategies for enhancing the sensitivity of electroanalytical methods. Usually, those strategies are based on the selection of the voltammetric technique, the inclusion of an accumulation step, and the ...
How to obtain kinetic information in thin-film voltammetry from the comparison of SCV and SWV responses
(Elsevier Science SA, 2020-12)
Thin-film voltammetry (TFV) has one of the simplest experimental setups for studying the electrochemical processes that take place at liquid/liquid interfaces. This is because in TFV it is possible to neglect the iR drop ...
Theory of square-wave voltammetry for the analysis of a CE reaction mechanism complicated by the adsorption of the reactant
(Elsevier Science SA, 2019-11)
This manuscript presents a theoretical work about an electrode process preceded by a chemical reaction involving adsorbed species and where both reactions can present any degree of reversibility. The electrode reaction ...
Theory of square-wave voltammetry for the analysis of an EC reaction mechanism complicated by the adsorption of the reagent
(Elsevier Science Sa, 2019-05-27)
A theoretical model about the voltammetric response of electrode processes complicated by adsorption of reactant and a following coupled chemical reaction of soluble species (E (ad) C (sol) mechanism) is presented. The ...
Adsorption of ochratoxin A (OTA) anodic oxidation product on glassy carbon electrodes in highly acidic reaction media: Its thermodynamic and kinetics characterization
(PERGAMON-ELSEVIER SCIENCE LTD, 2010-01-01)
We study the thermodynamics and kinetics of the adsorption of a redox couple having quinone nature on glassy carbon electrodes. This couple is produced by the anodic oxidation of mycotoxin ochratoxin A in 10% acetonitrile ...
Electrochemical oxidation of butein at glassy carbon electrodes
(Elsevier, 2013-01-23)
The electrochemical oxidation of flavonoid butein is studied at glassy carbon electrodes in phosphate and citrate buffer solutions of different pH values, and 1M perchloric acid aqueous solutions by cyclic and square wave ...
Characterization of the surface redox process of adsorbed morin at glassy carbon electrodes
(Pergamon-Elsevier Science Ltd, 2011-02)
The thermodynamic and kinetics of the adsorption of morin (MOR) on glassy carbon (GC) electrodes in 0.2 moldm−3 phosphate buffer solutions (PBS, pH 7.00) was studied by both cyclic (CV) and square wave (SWV) voltammetries. ...
Characterization of the surface redox process of caffeic acid adsorbed at glassy carbon electrodes modified with partially reduced graphene oxide
(Elsevier, 2016-12)
This paper describes for the first time the caffeic acid (CA) electrochemical oxidation in 1.0 M HClO4 and phosphate buffer solutions (PBS) of different pH at glassy carbon electrodes (GCE) modified with electrochemically ...
Theory of square-wave catalytic adsorptive stripping voltammetry. How to obtain mechanistic information from experimental data
(Elsevier Science Sa, 2018-10)
The sensitivity of a catalytic adsorptive stripping voltammetric method depends mainly on the strength of adsorption of the electroactive reactant and the efficiency of the catalytic reaction. While the strength of adsorption ...
