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.

Adsorptive stripping voltammetry of chromium 1,5‐diphenylcarbazonate
Electroanalysis, 1991AbstractElectrochemical transformations of chromium 1,5‐diphenylcarbazonate (the complex), absorbed on the surface of a graphite electrode from a solution of 0.15 M sulfuric acid, were studied. The complex was synthesized by mixing acetone solutions of CrCl3·6H2O and diphenylcarbazone, as well as aqueous solutions of K2Cr2O7 and aqueous acetone ...

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.

Determination of palladium by adsorptive stripping voltammetry
Fresenius' Journal of Analytical Chemistry, 1997Adsorptive accumulation of the Pd(II) complex with dimethylglyoxime was evaluated for stripping voltammetry with respect to different parameters. The sensitivity of the method and the linearity between the peak current and the concentration of Pd(II) depends on the ionic strength, the electrode area, the preconcentration time, the transport rate to the

Adsorptive stripping voltammetry of bovine serum albumin
Analytica Chimica Acta, 1988Abstract The behaviour of bovine serum albumin in cyclic voltammetry and differential-pulse adsorptive stripping voltammetry is described. Under the optimized conditions, with an accumulation potential of +0.15 V (vs. Ag/AgCl) and accumulation times of 50 s or 120 s, linear calibration graphs were obtained for 1.0–4.0×10 −8 M BSA and 0.2–1.5×10 −8 ...

Square-wave adsorptive cathodic stripping voltammetry of pantoprazole
Journal of Pharmaceutical and Biomedical Analysis, 2003Adsorption 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 square-wave voltammetry of DNA
Journal of Electroanalytical Chemistry, 1997Abstract Faradaic currents produced by DNA at neutral pH are studied by square-wave voltammetry (SWV) in connection with an HMDE. Under these conditions single-stranded DNA produces a cathodic peak (due to the reduction of adenine and cytosine residues) which is better developed than the peak obtained by CV and DPV; the SWV peak can thus be measured ...

Determination of Dinoseb by adsorptive stripping voltammetry
Electroanalysis, 1991AbstractA sensitive method is described for the determination of Dinoseb (2‐sec‐butyl‐4, 6‐dinitrophenol) at nanomolar levels by adsorptive stripping voltammetry (AdSV) at the hanging mercury drop electrode. Cyclic voltammetry studies showed two well‐defined reduction peaks, at −0.21 and −0.36 V, and demonstrated the adsorption of Dinoseb and its ...

Adsorptive/Extractive Stripping Voltammetry of 1,2,3,4-Tetrahydrocarbazole
Analytical Letters, 1985Abstract Adsorptive/extractive accumulation of 1,2,3,4-tetrahydrocarbazole at a carbon paste electrode is used to improve the subsequent voltammetric measurement with respect to sensitivity and selectivity. By simply immersing the electrode in the 1,2,3,4-tetrahydrocarbazole solution for a given period of time, and then transferring it to a blank ...

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.
