Theory of differential normal pulse voltammetry

Electrochimica Acta, 1982
Abstract An analytical solution is presented for the case of double potential step chronoamperometry at a stationary planar electrode for the case of heterogeneous charge transfer control. Extension of the result to multiple potential steps gives the current—potential response for differential normal pulse voltammetry.

Thin-layer differential pulse voltammetry

Analytical Chemistry, 1977
The applicability of differential pulse anodic stripping voltammetry to thin-layer electrodes is demonstrated with PbZ+, CdZ+, Zn2+, CuZf, and TI'. Typical calibration curves are linear over a range of 30 to 600 ng/mL with a detection limit of 10 ng/mL. Samples of blood, soybean, and oyster were analyzed for lead.

Potentiality of PARAFAC approaches for simultaneous determination of N-acetylcysteine and acetaminophen based on the second-order data obtained from differential pulse voltammetry.

Talanta: The International Journal of Pure and Applied Analytical Chemistry, 2019
N-acetylcysteine (N-AC) has widespread application such as pharmaceutical drug and nutritional supplement. Its adverse effects are rash, urticaria, and itchiness and large doses of N-AC could potentially cause damage to the heart and lungs. Therefore, in

Reverse Differential Pulse Voltammetry and Polarography

Analytical Chemistry, 1995
In this paper we obtain the analytical solution for the reverse differential pulse (RDP) technique for a slow electronic transfer process, starting from expressions obtained previously for the faradaic response to a triple potential pulse. The solutions are valid for the planar approximations of a static mercury drop electrode and of a dropping mercury

Differential pulse voltammetry at microdisk electrodes

Electrochimica Acta, 2005
Expressions for reversible differential pulse (DP) voltammograms at microdisk electrodes were established from experimental results as a function of pulse electrolysis parameters. Three expressions were computed numerically, depending on the electrode radius and varying the pulse interval, tau.

Multielement determination in biological materials by differential pulse voltammetry

Analytical Chemistry, 1985
A simple and reliable multielement approach for the determination of up to eight elements in a single biological sample digest at major, minor, trace, and/or ultratrace levels has been developed. The method employs a wide range of voltammetric techniques such as polarography, cathodic stripping, anodic stripping, and adsorption voltammetry in their ...

Differential Pulse Voltammetry on Spherical Microelectrodes

Electroanalysis, 1999
A theory of differential pulse voltammetry (DPV) and polarography (DPP) of reversible redox reaction on the spherical electrode is developed. Numerical solutions for DPV peak currents and peak potentials are compared with analytical solutions obtained for DPP and satisfactory agreement is found when the period between pulses is more than five times ...

Differential linear scan voltammetry: analytical performance in comparison with pulsed voltammetry techniques

Analytical and Bioanalytical Chemistry, 2013
We report here on differential linear scan voltammetry, DLSV, that combines the working principles of linear scan voltammetry, LSV, and the numerous existing pulsed voltammetry techniques. DLSV preserves the information from continuous interrogation in voltage and high accuracy that LSV provides about electrochemical processes, and the much better ...

Determination of cadmium by differential pulse adsorptive stripping voltammetry

Journal of Pharmaceutical and Biomedical Analysis, 2000
A study of the adsorptive stripping voltammetry of cadmium on a mercury drop electrode is reported in which 2-mercapto-5-phenyl-amino-1,3,4-thiadiazole (MPATD), synthesized at home has been used as a chelating agent. The most suitable operating conditions and parameters such as buffer, pH, deposition potential, deposition time, ligand concentration ...
