Determination of iron by anodic stripping voltammetry

Journal of Electroanalytical Chemistry, 1970
Summary A chemical exchange reaction between ferric iron and bismuth-EDTA at pH 4.0 is used to determine iron by anodic stripping voltammetry. The rotating electrode was a highly polished glassy carbon disc, coated in situ with mercury by the addition of mercuric ions to the sample solution. No other common metal ion enters into the exchange reaction,

A contribution to the use of chelating agents in anodic stripping voltammetry

Talanta, 1971
The E(p)/(2), values of the ions Pb(2+), Bi(3+), Cu(2+), Cd(2+), Tl(+) were determined by means of cyclic voltammetry in solutions of acetate and Britton-Robinson buffers and in solutions containing EDTA and DCTA. DCTA was then utilized in the determination of small amounts of bismuth, down to 10(-7)M, in the presence of 10(4) times as much lead, and ...

MEASURING BIOAVAILABLE COPPER USING ANODIC STRIPPING VOLTAMMETRY

Environmental Toxicology and Chemistry, 1996
AbstractSince speciation can affect bioavailability and toxicity of copper in aquatic systems, accurate predictions of effects of bioavailable forms require detection and/or measurement of these forms. To develop an approach for measurement of bioavailable copper, a copper sulfate solution (CuSO4·3Cu(OH)2·H2O) was used in 10-d aqueous and sediment ...

Underpotential deposition and anodic stripping voltammetry at mesoporous microelectrodes

The Analyst, 2005
Using the technique of liquid crystal templating a series of high surface area mesoporous platinum microelectrodes was fabricated. The underpotential deposition of metal ions at such electrodes was found to be similar to that at conventional platinum electrodes. The phenomena of underpotential deposition, in combination with the intrinsic properties of

Application of sequential injection analysis to anodic stripping voltammetry

Talanta, 1997
Sequential injection analysis (SIA) technique has been applied to anodic stripping voltammetry (ASV). The sample and reagent volumes can easily be controlled by SIA. The technique also allows plating of the mercury film on-line and therefore substantially reduces generation of mercury containing waste.

Anodic Stripping Voltammetry Using a Vibrating Electrode

Electroanalysis, 2007
AbstractThis work proposes a vibrating microwire electrode as working electrode in stripping voltammetry. The vibration was found to maintain a constant and thin (1–2 μm) diffusion layer during the deposition step. The electrode vibration eliminated the need for external stirring of the solution, thus facilitating in situ detection in the environment ...

Selective method for the determination of gold by anodic stripping voltammetry

Analytical and Bioanalytical Chemistry, 1996
A highly selective method for the deter- mination of gold by anodic stripping voltammetry is described. For preconcentration a glassy carbon electrode, activated by deposition of small amounts of gold before the measurement, is proposed. The Au(3+) reduction process at such an electrode is effective starting with the potential +0.4 V vs.
