Trace measurements of rhodium by adsorptive stripping voltammetry
Talanta, 1991A sensitive stripping voltammetric procedure for quantifying rhodium is described. The complex of rhodium with chloride ions is adsorbed on the hanging mercury drop electrode, and the reduction current of the accumulated complex is measured during a negative-going scan. Cyclic voltammetry is used to characterize the interfacial and redox behaviors. The

Trace measurements of colchicine by adsorptive stripping voltammetry
Talanta, 1990A highly sensitive voltammetric method for trace measurements of the alkaloid colchicine is described. The method is based on the controlled adsorptive accumulation of the drug at the hanging mercury drop electrode, followed by voltammetric determination of the surface species.

Trace measurement of dipyridamole by adsorptive stripping voltammetry
Talanta, 1993A sensitive adsorptive stripping voltammetric method for trace measurement of dipyridamole in alkaline solution is described. The method is based on the adsorptive accumulation of the drug at the hanging mercury drop electrode, followed by linear sweep voltammetric determination.

Determination of trichlorobiphenyl by adsorptive stripping voltammetry
Analytica Chimica Acta, 1984Abstract Trichlorobiphenyl is determined in the concentration range 0.004–1 mg l −1 by adsorptive stripping voltammetry at a hanging mercury drop electrode. Preconcentration is achieved by adsorption at a potential of −0.40 (V (vs. Ag/AgCl), and desorption at −1.10 V.

Determination of uranium by adsorptive stripping voltammetry
Analytica Chimica Acta, 1983Abstract A voltammetric method for the determination of uranium in natural waters in the concentration range from 0.4 μg 1 −1 to 0.2 mg 1 −1 is described. The method is based on adsorptive accumulation of the uranium(VI)—pyrocatechol complex on the hanging mercury drop electrode followed by the reduction of the absorbed complex.

Analytical Proceedings including Analytical Communications, 1994
Stripping voltammetric methods involve both accumulation and determination steps, and sometimes intermediate steps. Ideally it would be helpful if nomenclature could be found which gave information on the nature of all of the steps involved. Possible combinations of accumulation and determination methods in stripping voltammetry are considered here.

Determination of bilirubin by adsorptive stripping voltammetry
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1985Abstract A stripping method for the determination of bilirubin at the submicromolar and nanomolar concentration levels is described. The method is based on controlled adsorptive accumulation of bilirubin at the static mercury drop electrode followed by differential pulse measurement of the surface species.

Adsorptive stripping voltammetry of trace thallium
Analytica Chimica Acta, 1993Abstract A highly selective and sensitive adsorptive stripping voltammetric procedure for trace measurements of thallium in presence of o -cresolphthalein (OCP) is described. The response is not affected by the presence of excess tin, lead or indium, which can interfere severely in analogous anodic stripping measurements.

Adsorptive Stripping Voltammetry of Environmental Carcinogens
Current Analytical Chemistry, 2008This review describes our recent results regarding adsorptive stripping voltammetric determination of submicromolar and nanomolar concentrations of various environmentally important chemical carcinogens using both traditional (hanging mercury drop electrode, carbon paste electrode) and non-traditional types of electrodes (solid amalgam electrodes ...
