Anodic Stripping Voltammetry Using Nanoelectrodes
ECS Meeting Abstracts, 2014Anodic stripping voltammetry is an important technique for the detection of trace metals. The technique is very sensitive but requires careful control of a range of parameters including the conditioning of the working electrode, the temperature and the hydrodyanamics. In theory nanoelectrodes are immune to stirring and thus this parameter ought to be

The determination of gold by anodic stripping voltammetry
Analytica Chimica Acta, 1988Abstract A method is described for the routine determination of gold as its chloride or cyanide complex by anodic stripping voltammetry at a glassy carbon electrode coupled to a microprocessor-controlled voltammeter. The preferred supporting electrolyte is 0.1 M HCl/0.32 M HNO3, with plating at −200 mV or −1200 mV (vs. Ag/AgCl).

Determination of copper and lead in schist by anodic stripping voltammetry
Talanta, 1975Samples were decomposed in HClO(4)/HF mixture in a Teflon beaker to avoid electrochemical interference from platinum ions. The residue remaining after evaporation to dryness was taken up in nitric acid and examined by anodic stripping voltammetry. Both the hanging mercury drop electrode and the rotating glassy carbon electrode, mercury-plated in situ ...

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.

Determination of zinc in sea-water by anodic stripping voltammetry
Talanta, 1981The horizontal distribution of zinc in surface waters from Guanabara Bay has been studied by use of optimized voltammetric techniques and ultraclean working procedures. The non-linearity observed between the peak current for zinc and the electrolysis time, as well as the appearance of a peak at -1.16 V, are discussed. The values found for total zinc in

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.

Wall‐Jet electrode system for anodic stripping voltammetry
Electroanalysis, 1994AbstractA construction of an electroanalytical cell with a wall‐jet electrode (WJE) system consisting of a built‐in centrifugal pump and a thin mercury film‐covered glassy carbon stationary disk working electrode and its application to the differential pulse anodic stripping voltammetric measurements of traces of cadmium and lead are described ...

A pyrolytic carbon film electrode for voltammetry—IIIApplication to anodic-stripping voltammetry
Talanta, 1983The potential applicability of a pyrolytic carbon film electrode in the differential-pulse anodic-stripping voltammetric determination of cadmium and lead in sea-water is demonstrated. The performance at the 10(-10)M level is compared with that of a satisfactory glassy-carbon electrode.

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 ...
