Cyclic voltammetry of phenol

Journal of Analytical Chemistry, 2014
The possibility of phenol determination by cyclic voltammetry (CVA) on electrochemically modified glassy-carbon electrodes (GCE) was studied. The effect of the rate of linear potential sweep on the sensitivity of phenol determination was investigated. The adsorption nature of the analytical signal of phenol was revealed.

Cyclic staircase voltammetry

Journal of Electroanalytical Chemistry, 1977
Abstract The use of cyclic staircase voltammetry was investigated in order to study kinetic mechanisms at low concentration levels. The reversible case for c.s.c.v. was studied along with two common kinetic cases: e.c. and catalytic mechanism. For both the e.c.

VOLTAMMETRY | Linear Sweep and Cyclic

2005
Linear sweep voltammetry (LSV) and cyclic voltammetry (CV) are the most widely used voltammetric techniques for studying redox reactions of both organic and inorganic compounds because they are unmatched in their ability to provide information on the steps involved in electrochemical processes with only a modest expenditure of time and effort in the ...

Flow-injection cyclic voltammetry

Analytica Chimica Acta, 1988
Abstract A flow-injection cyclic voltammetry assembly is proposed which allows the performance of fast i-E scans and provides recordings similar to those obtained with photodiode array detectors. The arrangement is useful for qualitative and quantitative analysis, theoretical studies, and multicomponent determinations.

Basic instrumentation for fast cyclic voltammetry

Journal of Neuroscience Methods, 1988
Fast cyclic voltammetry is a new voltammetric technique which has been especially useful for measurements of dopamine release in vivo. This paper describes methods for the construction of a basic fast cyclic voltammetric amplifier, and the associated apparatus necessary to carry out fast cyclic voltammetric experiments.

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 ...

Is cyclic voltammetry above a few hundred kilovolts per second still cyclic voltammetry?

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1990
Abstract The development of ultramicroelectrodes and fast potentiostats in very recent years has allowed the investigation of electrochemical kinetics in the submicrosecond time scale by means of cyclic voltammetry at scan rates in the megavolt per second time scale.
