Cyclic voltammetry and differential pulse voltammetry of rescinnamine

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1986
Abstract 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, 1994
Abstract 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, 1983
The 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.

Determination of Cytochrome C, in Solution and in The Adsorbed State, by Differential Pulse Voltammetry (DPV).

Analytical Letters, 1995
We carried out the determination of cytochrome C, in solution and in the adsorbed state, using differential pulse voltammetry (DPV). The results obtained with DPV were compared with those obtained using cyclic voltammetry (CV).

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.

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

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 ...
