Additive Differential Pulse Voltammetry, Instead of Double Differential Pulse Voltammetry
Electrochemistry Communications, 2001 A new electrochemical double pulse potential technique called additive differential pulse voltammetry (ADPV) is proposed. This technique is inspired by the original idea of Birke et al. [Anal. Chem. 53 (1981) 852] of recording two differential pulse (DP) voltammograms and it consists of plotting the sum of these two signals versus the first pulse ...

Analytical Chemistry, 2006
The ion transfer across the water-solvent polymeric membrane interface is investigated by using a new device based on a modification of a commercial ion-selective electrode body that permits the accommodation of a platinum counter electrode inside the inner filling solution compartment and, therefore, use of a four-electrode potentiostat with ohmic ...

Differential Pulse Voltammetry on Spherical Microelectrodes
Electroanalysis, 1999A 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 Pulse Voltammetry
The Chemical Educator, 2015Differential Pulse Voltammetry (DPV) was utilized in this lab experiment to detect phenol with a carbon electrode modified with polyeugenol and compared to a bare carbon electrode in acidic and basic conditions. The peak potentials for phenol detection were dependent on the pH value of the phenol solution was found.

Differential normal pulse voltammetry — theory
Journal of Electroanalytical Chemistry, 1980Abstract The theory is presented of a modified form of differential pulse voltammetry, in which two potential steps with similar short duration are superimposed on the rest potential. Expressions for the current response to the double potential step are derived for quasireversible and totally irreversible charge-transfer processes of simple electrode

Cyclic voltammetry and differential pulse voltammetry of rescinnamine
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1986Abstract Two redox processes can be4 observed for rescinnamine by cyclic voltammetry. The electroactive group is identified as the 3,4,5-trimethoxycinnamic. A mechanism including a homogenous dimerization reacyion following the electron transfer is proposed for the redoz process which occurs at less negative potentials, and the rate constant for the ...

Double differential pulse voltammetry
Journal of Electroanalytical Chemistry, 1994Abstract From the solution obtained in previous work for the faradaic response to a triple pulse of potentials, the double differential pulse technique can be defined through the equation I ddp = i 3 − 2 i 2 + i 1 , where i j ( j = 1, 2, 3) is the current corresponding to the potential E j .

Evaluation of differential pulse voltammetry at carbon electrodes
Talanta, 1983The background and analytical responses of differential pulse voltammetry at carbon electrodes have been evaluated. Transient currents associated with small potential steps have been examined and are attributed mainly to redox reactions of various groups on the electrode surface.
