Hydrodynamically modulated voltammetry in microreactors
… electrochemical reactions by using cyclic voltammetry (CV) and large amplitude Fourier transformed alternating current voltammetry (FTACV) under microfluidic conditions. Single electron transfer reactions with different kinetics were studied first by using potassium ferrocyanide and …

Application of voltammetry to copper electrodeposition
… undertaken to determine the feasibility of using voltammetry and scanning electron microscopy techniques to characterize copper deposition from an acid-sulfate electrolyte. The main process variables investigated were temperature and addition agents (chloride ion, glue, separan or thiourea) at …

Fast Fourier transform square wave voltammetry
… digital data handling tool for square wave voltammetry. Theoretical square wave voltammogra.ms were examined to study the effect of experimental parameters in the spatial frequency domain. A new method was developed to determine truncation frequencies. A₀, the first spatial frequency, was …

Square-wave voltammetry detection for capillary electrophoresis
… an ECD system based on square-wave voltammetry was developed (CE-SWV). Detection limits obtained with CE-SWV for neurotransmitters (150 nM, S/N = 3) were comparable to those obtained using more fragile and complex amperometric CE detection systems. While CE-SWV worked well for …

A study of certain trace metals in sea water using anodic stripping voltammetry
Anodic stripping voltammetry utilizing a thin film mercury composite graphite electrode has been evaluated and applied for the direct analysis of the metals, Zn, Cu, Pb, and Cd in sea water. The electrode was observed to follow theoretical behavior for thin film electrodes and the technique was …

Stripping Voltammetry of Tellurium (IV) In 0.1M HC10 4 at Rotating Gold Disk Electrodes.
The stripping voltammetry of Tellurium (IV) in 0.1M HC10, using gold electrodes is described. Detection limits for solid gold, in situ gold-plated and externally gold-plated rotating glassy carbon disk electrodes are presented. No significant increase in sensitivity is reported for the use of solid …

Anodic Stripping Voltammetry of Tellurium (IV) in 1.0M NH4, SCN at Rotating Disk Gallium - Thin-Film Electrode.
… electroanalytical technique of anodic stripping voltammetry (ASV), using a gallium-thin film electrode in 1.0M NH4SCN at 60°C has been applied to study the electroanalytical chemistry of Te(IV). Both externally plated and in-situ plated thin-film gallium on rotating glassy carbon disk electrodes …
