Disposable and Sensitive Electrochemical Determination of Molnupiravir at a Pencil Graphite Electrode (PGE) by Differential Pulse Voltammetry (DPV)

Analytical Letters, 2023
This study describes the sensitive voltammetric determination of the COVID-19 drug, molnupiravir, at a pencil graphite electrode (PGE) which is easily available, inexpensive, disposable, and highly electrochemically active.

Investigation of the Hg(II) biosorption from wastewater by using garlic plant and differential pulse voltammetry.

Analytical Biochemistry, 2021
In this work, the bio sorption of mercury ion by garlic bio-adsorbent was studied. A batch and a continuous up-flow fixed-bed column system were used in this report. Differential pulse voltammetry was used to detecting the amount of mercury ion.

Differential normal pulse voltammetry — theory

Journal of Electroanalytical Chemistry, 1980
Abstract 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

Electrochemical detection of 3,4-methylenedioxymethamphetamine (ecstasy) using a boron-doped diamond electrode with differential pulse voltammetry: Simple and fast screening method for application in forensic analysis

, 2020
3,4-Methylenedioxymethamphetamine (MDMA) is an illicit stimulant drug also known as ‘ecstasy’ and is one of the most used amphetamines worldwide. Similar drugs to MDMA, so called as novel psychoactive substances (NPS), have been also found in seized ...

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 ...

Differential Pulse Voltammetry

The Chemical Educator, 2015
Differential 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.

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.
