Centri-voltammetry and biocentri-voltammetry: a review
Mikrochimica Acta, 2013 Centri-voltammetry and biocentri-voltammetry are techniques that combine centrifugation with voltammetry. This review covers (a) definitions; (b) experimental (cell) configurations; (c) effects of centrifugation parameters; and (d) applications of the method to the determination of heavy metals and biological molecules.

Microcells for voltammetry and stripping voltammetry
Talanta, 1997The designs and applications of "non-flow" microcells in voltammetry and stripping voltammetry for samples with volumes from sub-microliters to 5 ml are reviewed. The analysis of microcell designs was carried out on the basis of their classification: (i) microcells with a static sample, including thin-layer microcells with a static sample; (ii ...

Recent Advances in Voltammetry
ChemistryOpen, 2015 AbstractRecent progress in the theory and practice of voltammetry is surveyed and evaluated. The transformation over the last decade of the level of modelling and simulation of experiments has realised major advances such that electrochemical techniques can be fully developed and applied to real chemical problems of distinct complexity.

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 ...

Voltammetry at Micropipet Electrodes
Analytical Chemistry, 1998The use of micropipet electrodes for quantitative voltammetric measurements of ion-transfer (IT) and electron-transfer (ET) reactions at the interface between two immiscible electrolyte solutions (ITIES) requires knowledge of geometry of the liquid interface.

Voltammetry of Organic Microparticles
Mikrochimica Acta, 1999Solid microparticles of several different insoluble organic compounds were mechanically immobilized on the surface of graphite electrodes and immersed into a liquid electrolyte in order to stady their electrochemical reactions. Cyclic staircase voltammetry and square-wave voltammetry were used.

Anodic voltammetry of cefotaxime
Journal of Pharmaceutical and Biomedical Analysis, 1998In this study electrooxidation of cefotaxime was investigated using specially activated glassy carbon (GC), platinum and carbon paste (CP) electrodes in different supporting electrolyte solutions and at different pHs. The data revealed that the shapes of the voltammograms and the numbers of the oxidation steps changed depending on the nature of the ...

Abstract Voltammetry is the study of the current voltage relationships observed when electroactive species in solution are subject to oxidation or reduction at electrodes under carefully controlled conditions. This article describes the basic principle of voltammetry performed using the dropping mercury electrode (polarography).
