Correction of the induced charging current in staircase voltammetry
Analytica Chimica Acta, 1994Abstract Based on an electrolysis model and the analysis of the equivalent circuit, equations and procedures applicable to the correction of induced charging current for staircase voltammetry were derived. A system containing solutions of 0.25 mM ferrocene and 0.1 M tetraethylammonium tetrafluoroborate in acetonitrile was studied.

Conversion of Staircase Voltammetry to Linear Sweep Voltammetry by Analog Filtering
Analytical Chemistry, 1995The current responses for staircase voltammetry might be very different from those of true linear sweep voltammetry. This is particularly true for data from surface reactions. The existing theories for linear sweep voltammetry may not be used to interpret staircase voltammetric data.

Journal of Electroanalytical Chemistry, 1995
Abstract Differential pulse voltammetry (DPV) and related techniques are examined. The proposed treatment is valid for any pulse method performed at stationary plane or spherical electrodes in the case of simple reversible reactions with both redox forms soluble in solution.

Staircase cyclic voltammetry of electrocatalytic reaction inhibited by the product
Journal of Solid State Electrochemistry, 2020A model of electrocatalytic reaction influenced by the potential dependent inhibition is developed. The response of investigated mechanism is anomalous voltammogram consisting of two anodic peaks. The relationship between two peak currents and the parameters of electrode reaction was analysed theoretically.

Comparison of linear sweep and staircase voltammetries using walsh series
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1986Abstract Theories of linear sweep voltammetry and staircase voltammetry are shown to be equivalant for a reversible system under semi-infinite linear diffusion. This equivalence is demonstrated by using a Walsh series approximation for the potential profile involved in the integrals which arise in the theory for linear sweep voltammetry.

Staircase voltammetry and pulse polarography with a microcomputer-controlled polarograph
Analytica Chimica Acta, 1980Abstract A microcomputer, based on the 6502 microprocessor, is applied to the operation and data acquisition with staircase voltammetry and pulse polarography. Results for the reduction of cadmium(II) closely follow theoretical trends, indicating that the approach is a viable alternative to existing analog instruments and more costly minicomputer ...

Internal reflectance spectroscopy associated with cyclic staircase voltammetry using a microcomputer
Analytica Chimica Acta, 1982Abstract In order to obtain extensive information on electrode-solution interfaces, a rapid-scan internal reflectance spectroscopic system is combined with cyclic staircase voltammetry; the staircase wave generated by computer software is applied to an optically transparent tin oxide electrode.

Inactivation of redox enzymes and the loss of enzyme’s material from its adsorbed film on electrode surface are events that have similar outputs when studied under conditions of protein-film voltammetry. In the current work, we present a series of novel theoretical results under conditions of protein-film cyclic staircase voltammetry that clearly ...
