Bismuth-Coated Carbon Electrodes for Anodic Stripping Voltammetry
Analytical Chemistry, 2000Bismuth-coated carbon electrodes display an attractive stripping voltammetric performance which compares favorably with that of common mercury-film electrodes. These bismuth-film electrodes are prepared by adding 400 microg/L (ppb) bismuth(III) directly to the sample solution and simultanously depositing the bismuth and target metals on the glassy ...

The determination of trace metals in sweat by anodic stripping voltammetry
Science of The Total Environment, 1987Sweating was induced on the forearm of subjects by pilocarpine iontophoresis, and the sweat collected on a small membrane filter. Zinc, cadmium, lead and copper were then determined in the filter by anodic stripping voltammetry (ASV) using one of two alternative techniques: leaching the filter with a supporting electrolyte (0.1 M NaNO3/0.002 M HNO3 ...

Evaluation of “labile” metal in sediments by anodic stripping voltammetry
Talanta, 1990A procedure for determining the "labile" metal content of contaminated sediments (in different chemical environments) has been critically examined. The sediments were extracted overnight with different chemical solutions and the suspensions were analysed by differential pulse anodic stripping voltammetry.

Measurement of Ultrasmall Volumes Using Anodic Stripping Voltammetry
Analytical Chemistry, 2002This paper discusses a new and effective method for small volume determination. The benefits of working with small volumes are numerous and include using less material, generating less waste, increased functionality in less space, portability, and high throughput. As sample size decreases, measuring its volume becomes more challenging.

A contribution to the use of chelating agents in anodic stripping voltammetry
Talanta, 1971The 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 ...

Anodic Stripping Voltammetry Using a Vibrating Electrode
Electroanalysis, 2007AbstractThis 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 ...

Anodic stripping voltammetry of tungsten at graphite electrodes
Electroanalysis, 1996AbstractTrace levels of tungsten can be determined at a graphite electrode using anodic stripping voltammetry. Tungsten is concentrated at the electrode surface after reduction to Wv as a insoluble ternary complex in the presence of rhodanide ions and antipyrine (ANT) or 4‐ dimethyl‐aminoantipyrine (pyramidon, PYR).

Selective method for the determination of gold by anodic stripping voltammetry
Analytical and Bioanalytical Chemistry, 1996A 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.
