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

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 .

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 ...

Thin-layer differential pulse voltammetry
Analytical Chemistry, 1977The 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.

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 ...

Differential pulse voltammetry study of gadolinium-DTPA complex
Research Journal of Chemistry and Environment, 2022The rare earth element (REE) is a group of elements with extensive use. One of the most used REEs is gadolinium (Gd) that is widely used as contrast agent. Gd complexes commonly used as contrasting compounds are Gd-DTPA. Gd-DTPA has been widely used in the health sector to diagnose various diseases because it is safe for the body and only gives mild ...

Reverse Differential Pulse Voltammetry and Polarography
Analytical Chemistry, 1995In 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

Theory of differential normal pulse voltammetry
Electrochimica Acta, 1982Abstract 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.
