Application of Elimination Voltammetry to Adsorptive Stripping of DNA

Electroanalysis, 2000
Adsorptive 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 ...

Adsorptive Stripping Voltammetry of Bleomycin

The Analyst, 1997
In 0.05 M H2SO4 solution, two reductive peaks, P1 and P2, of bleomycin were obtained. The peak potentials E(P1) and E(P2) were -0.83 and -1.09 V (versus Ag/AgCl), respectively. The sensitivity of P2 was much higher than that of P1. The peak current of P2 was proportional to the concentration of bleomycin over the range 1.0 x 10(-9)-1.0 x 10(-7) M with ...

Determination of gallium by adsorptive stripping voltammetry

Talanta, 2004
A procedure for the determination of gallium by differential pulse adsorptive stripping voltammetry (DPADSV), using different complexing agents (ammonium pyrrolidine dithiocarbamate (APDC), pyrocatechol violet (PCV) and diethyldithiocarbamate (DDTC)), has been optimized.

Cathodic stripping voltammetry and adsorptive stripping voltammetry of selenium(IV)

Analytica Chimica Acta, 1988
Abstract Cathodic stripping voltammetry of selenium(IV) in 0.1 M hydrochloric acid media yielded a nonlinear calibration graph for the concentration range 10−9−10−8 M. In this concentration range, adsorptive stripping voltammetry based on adsorption of the selenium/3,3′-diaminobenzidine complex on the surface of the hanging mercury drop electrode at ...

Adsorptive Stripping Voltammetry of Phytohemagglutinin

Analytical Letters, 1988
Abstract The adsorptive stripping voltammetric behaviour of the lectin, phytohemagglutinin, has been optimised with respect to accumulation time, accumulation potential, pulse amplitude, scan rate and drop size. Adsorptive stripping voltammetry has also been used to study the interaction of this protein with nannose, galactose and N-acetyl-D ...

Determination of cardiac glycosides by adsorptive stripping voltammetry

The Analyst, 1985
Several cardiac glycosides are shown to adsorb strongly on to mercury electrodes. Using this phenomenon to accumulate these compounds at the static mercury-drop electrode prior to differential-pulse voltammetric measurements, nanomole sensitivities are readily achieved.

Trace measurements of colchicine by adsorptive stripping voltammetry

Talanta, 1990
A 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, 1993
A 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.

Trace measurements of rhodium by adsorptive stripping voltammetry

Talanta, 1991
A 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

Determination of trichlorobiphenyl by adsorptive stripping voltammetry

Analytica Chimica Acta, 1984
Abstract 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.
