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 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.

Determination of Melphalan Using Differential Pulse Voltammetry
Analytical Letters, 1985Abstract The anodic oxidation of melphalan was studied on a glassy carbon disk electrode, either stationary or rotated, using a d.c. and a differential pulse potential program. The conditions have been found for a differential pulse voltammetric determination of the substance, with a detection limit of 1 × 10−6 mol 1 ...

Determination of olsalazine sodium in pharmaceuticals by differential pulse voltammetry.
Die Pharmazie, 2001 The electrochemical oxidation of olsalazine sodium was investigated by cyclic, linear sweep, differential pulse and square wave voltammetry using glassy carbon disc electrode in different buffer systems. Best results were obtained for the determination of olsalazine using the differential pulse voltammetric technique in phosphate buffer at pH 7.0.

Determination of paracetamol in tablets and blood plasma by differential pulse voltammetry
Journal of Pharmaceutical and Biomedical Analysis, 1988Paracetamol, also known as acetaminophen (APAP) (N-acetyl-p-aminophenol), is a widely used non-narcotic analgesic and antipyretic agent. The determination of paracetamol is important for assessing stability for therapeutic monitoring and for possible toxicological effects.

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
