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 ...

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-catalytic stripping voltammetry for determination of ultratrace titanium
Talanta, 1994An extremely sensitive stripping voltammetric procedure for determination of ultratrace titanium is reported. The method is based on the interfacial preconcentration of titanium-cupferron complex onto the hanging mercury drop electrode, followed by catalytic reduction of the adsorbed complex for the presence of cupferron. The peak currents are directly

Speciation of antimony by adsorptive stripping voltammetry using pyrogallol
Talanta, 2007This paper describes a new procedure for the determination of Sb (III) and Sb (V) by differential pulse adsorptive stripping voltammetry (DPAdSV) using pyrogallol as a complexing agent. The selection of the experimental conditions was made using experimental design methodology.

Adsorptive stripping voltammetry of a fentanyl derivative at a mercury electrode
Talanta, 1994In a supporting electrolyte of NaOH, a pair of cathodic and anodic peaks of N,N'-diphenyl-N,N'-bis(1-phenylmethyl-4-piperidinyl)-ethanediamide (DBPPE) is found by cyclic voltammetry at a Hg electrode. The cathodic and anodic peak potentials are -1.53 and -1.46 V (vs. Ag/AgCl), respectively.

Determination of cadmium by differential pulse adsorptive stripping voltammetry
Journal of Pharmaceutical and Biomedical Analysis, 2000A study of the adsorptive stripping voltammetry of cadmium on a mercury drop electrode is reported in which 2-mercapto-5-phenyl-amino-1,3,4-thiadiazole (MPATD), synthesized at home has been used as a chelating agent. The most suitable operating conditions and parameters such as buffer, pH, deposition potential, deposition time, ligand concentration ...

Determination of traces molybdenum by catalytic adsorptive stripping voltammetry
Talanta, 2005A reliable and very sensitive procedure for the determination of ultra trace of molybdenum is proposed. Molybdenum was determined by cathodic stripping differential pulse voltammetry based on the adsorption collection of the Mo(VI)-Tiron complex on a hanging mercury drop electrode (HMDE).

Application of Elimination Voltammetry to Adsorptive Stripping of DNA
Electroanalysis, 2000Adsorptive stripping voltammetry has been extended by elimination voltammetry with linear scan rate (EVLS). EVLS offers the elimination of selected currents from the linear scan voltammetry results. It can be achieved by an elimination function formed by a linear combination of total currents measured at different scan rates, because the basic idea of ...

Fast adsorptive stripping voltammetry of iron in oxygenated seawater
Electroanalysis, 1996AbstractA fast adsorptive stripping voltammetric procedure for the determination of ultratrace amounts of iron in unpurged oceanic waters is reported. The method is based on that developed by van den Berg et al. [l]. It was modified to increase the sensitivity, to measure in the presence of oxygen and to reduce drastically the analysis time at the ...

Determination of medecamycin by adsorptive stripping voltammetry with an activated electrode
Analytical and Bioanalytical Chemistry, 2004The adsorptive and electrochemical behaviors of medecamycin were investigated on a glassy carbon electrode (GCE) pretreated by anodic oxidation at +1.8 V for 5 min in 0.025 mol l(-1) NH(3)-NH(4)Cl (pH 8.6) solution. An adsorptive stripping voltammetric method for the determination of medecamycin at the pretreated glassy carbon electrode has been ...
