Isopotential points in reverse square-wave voltammetry

Journal of Electroanalytical Chemistry, 2009
Isopotential points in reverse square-wave voltammetry of irreversible electrode reactions are described for the first time. Experimental results (obtained with Eu3+ in perchlorate solutions) and model calculations indicate that such an intersection appears when the net signals, recorded at increasing step potential, are plotted together.

Square-wave voltammetry of an aqueous solution of indigo

Journal of Electroanalytical Chemistry, 2000
Indigo is dissolved in water in the concentration of 5×10-5 mol/L and measured by highly sensitive adsorptive stripping square-wave voltammetry in order to determine the parameters of its electrochemical reduction. The formal potential of indigo/leucoindigo redox couple dissolved in the aqueous 0.7 mol/L KNO3, pH 12 (NaOH) is -0.566 ą 0.003 V vs Ag ...

Square‐wave Amplitude Effect in Cathodic and Anodic Stripping Square‐wave Voltammetry

Electroanalysis, 2018
AbstractIn this paper a theoretical study of stripping processes at planar electrodes under conditions of square‐wave voltammetry is presented. A mechanistic examination for cathodic stripping electrode mechanisms, a simple anodic striping mechanism, and anodic stripping mechanisms coupled with adsorption equilibrium of the analyte are discussed using ...

Square-wave voltammetry of some bipyridinium oximes

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1990
Abstract Four bis(1-methylpyridinium) oximes (toxogonin, HS-6, HI-6 and HGG-12, see Scheme 1) were analysed by square-wave voltammetry from l M aqueous solutions of NaNO 3 . Britton-Robinson buffers and HNO 3 , were used for pH adjustments between 1 and 10. In acidic media, the oximes exhibit two (toxogonin, HS-6 and HGG-12) or four (HI-6) SWV peaks.

Determination of Stevioside by Square-wave Voltammetry

2010
Steviol glycosides are electroactive compounds and can be detected by mercury electrode. The maxima of square-wave voltammograms of steviol and stevioside appear at -1.3 V vs Ag/AgCl in 1 M NaCl at approximately pH 11. The responses are quasireversible and probably caused by electro-reduction of carboxyl, or ester groups, respectively.
