The electrochemical behavior of thallium was studied on glassy carbon electrodes in sulfate solutions. Cyclic voltammetry was used to study the kinetics of the electrode processes and to determine the nature of the limiting step of the cathodic reduction of thallium ions. According to the dependence of current on stirring rate and scan rate, this process is diffusion limited. Chronocoulometry s...

Poly 8-(3-acetylimino-6-methyl-2,4-dioxopyran)-1-aminonaphthalene (PAMDAN) films were electrodeposited on platinum electrode (Pt), forming PAMDAN/Pt modified electrode, to study its utility in electrooxidation of iodide ion. The electrooxidation process was investigated by cyclic voltammetry. The effects of different factors e.g. scan rate, iodide ion concentration, film thickness and acid conc...

The electrochemical behavior of the cation exchange polymer Nation containing tetrathiafulvalenium (TTF +) on a platinum sub strate is described. The polymer electrode shows cyclic voltammetric behavior similar to that of solid films of TTF on platinum. In 1.0M KBr the oxidized form of the electroactive molecules in the polymer (TTF § forms nonstoichiometric complexes with Br-. The peak potenti...

The electrochemical deposition of polyaniline nanofibers and nanoparticles have been investigated on gold electrodes by cyclic voltammetry and their morphology by high resolution scanning electron microscopy and atomic force microscopy. The type and dimensions of the nanostructures obtained depend on deposition conditions such as monomer concentration, scan rate and electrical potential. We hav...

Fast Scan Cyclic Voltammetry (FSCV) relies on detection of amperometric changes resulting from specific oxidation and reduction events during rapid voltage cycling on an implanted carbon fiber electrode (CFE). Previous systems have documented FSCV recording for detection of dopamine[1], norpeinepherine[2] and serotonin[3] using both tethered[1] & wireless[2,4,5] recording devices. We have devel...

Introduction Glucose level can be monitored using fast scan cyclic voltammetry (FSCV) [1][2]. The FSCV is known to have better chemical resolution than conventional sensors. [2] The FSCV can be implemented wirelessly [3]. However, the latter system is based on Bluetooth unit which requires a battery in the internal unit. We propose a method for wireless transmission of FSCV where the internal u...

We report direct electrochemistry of the iNOS heme domain in a DDAB film on the surface of a basal plane graphite electrode. Cyclic voltammetry reveals FeIII/II and FeII/I couples at -191 and -1049 mV (vs Ag/AgCl). Imidazole and carbon monoxide in solution shift the FeIII/II potential by +20 and +62 mV, while the addition of dioxygen results in large catalytic waves at the onset of FeIII reduct...

The theory of cyclic voltammetry is presented for chemical reactions coupled with electron transfer reactions. A numerical method is described for solving integral equations derived from the appropriate boundary value problems. New correlations make it possible to characterize unknown systems by studying the variation of peak current, half-peak potential, or ratio of anodic to cathodic peak cur...
