Adsorptive stripping voltammetry for the determination of nifedipine in human serum

Talanta, 1989
Adsorptive stripping voltammetry is used for the determination of trace levels of nifedipine. The conditions for preconcentration on the mercury drop electrode have been studied and the final measurements are made by differential pulse voltammetry.

On-line determination of vanadium by adsorptive stripping voltammetry

Analytica Chimica Acta, 1995
Abstract An on-line electrochemical stripping procedure for trace determination of vanadium was developed combining the advantages of adsorptive stripping voltammetry with flow injection analysis. The vanadium formed a complex with cupferron in an acetate buffered solution which adsorbed onto the mercury film electrode.

Indirect determination of surfactants by adsorptive stripping voltammetry

Analytica Chimica Acta, 1986
Abstract The effect of some anionic, cationic and nonionic surface-active substances on the suppression of adsorptive accumulation of the bis(dimethylglyoximato)nickel(II) complex, Ni(DMG) 2 , is described. Competitive adsorption of surfactants can be used to determine surfactants commonly used in commercial detergents.

Square-wave adsorptive cathodic stripping voltammetry of pantoprazole

Journal of Pharmaceutical and Biomedical Analysis, 2003
Adsorption and reduction of pantoprazole were investigated by cyclic and square-wave voltammetry on a hanging mercury drop electrode in Britton-Robinson buffers at pH 2.0-11.0. The reduction process gave rise to a single peak within the entire pH range.

Adsorptive stripping voltammetry in pharmaceutical analysis

1992
The use and advantages of adsorptive stripping voltammetry at the hanging mercury drop electrode in pharmaceutical analysis are discussed and the generally applicable procedure is given. The main advantages are increased sensitivity, selectivity and low cost. Various studies on this subject since 1984 are reviewed.
