Individual and simultaneous electrochemical detection of iodide and iodine has been performed via cyclic voltammetry on boron doped diamond (BDD) electrodes in a 1M NaClO(4) (pH 8) solution, representative of typical environmental water conditions. It is feasible to compute accurate calibration curve for both compounds using cyclic voltammetry measurements by determining the peak current intens...

It is exactly one hundred years ago when the first paper about development of polarography was published in 1922. Polarography considered a predecessor voltammetry, and this iconic electrochemical technique designed by Nobel laureate Jaroslav Heyrovsky. In short review, aim to highlight some most important achievements voltammetry so far. While hints are given theoretical works related various ...

Oxidative stress plays a pivotal role in the pathogenesis of many diseases, but there is no accurate measurement oxidative or antioxidants that has utility clinical setting. Cyclic Voltammetry an electrochemical technique been widely used for analyzing redox status industrial and research settings. It also recently applied to assess antioxidant vivo biological samples. This systematic review id...

a novel chemically modified electrode containing prussian blue complex was achieved on the surface of glass carbon electrode by sol-gel technique. the electrochemical behavior of modified electrode was characterized by cyclic voltammetry in detail. the film electrode obtained was very stable and exhibited electrocatalytic response for oxidation of nitrite. results showed at bare gc electrode, a...

the reactions of interest occur at the surface of the working electrode. Therefore, we are interested in controlling the potential drop across the interface between the surface of the working electrode and the solution (i.e., the interfacial potential). However, it is impossible to control or measure this interfacial potential without placing another electrode in the solution. Thus, two interfa...

The widely employed electroanalytical technique of adsorptive stripping voltammetry (AdsSV) is critically assessed and evaluated at a wide diverse range unmodified nano-particle modified carbon electrodes using the analyte fipronil as paradigmatic case. generic performances are investigated compared with revealing similar LOD values pointing to intrinsic limitations AdsSV arising from non-indep...

ABSTRACT The use of square wave voltammetry (SWV) and square wave adsorptive stripping voltammetry (SWAdSV) in conjunction with a cyclic renewable silver amalgam film electrode for the determination of flumetralin is presented. Poor separation of two overlapped reduction peaks is significantly improved when hexadecyltrimethylammonium bromide is used as a component of the supporting electrolyte ...

Modification of a glassy carbon (GC) electrode surface by adhered microparticles of zinc oxide (ZnO) using electrochemical performance of microparticles of ZnO/GC electrode shows excellent electrocatalytic activity towards the oxidation of ascorbic acid in 0.1 M KH2PO4 electrolyte solution by cyclic voltammetry (CV). This paper seeks to critically examine the modification of GC electrode with Z...
