Chronopotentiometric stripping analysis using gold electrodes, an efficient technique for mercury quantification in natural waters
(Wiley-Blackwell, 2005-05-01)
This paper proposes a simple methodology for mercury quantification in natural water by stripping chronopotentiometry at constant current, using gold (film) electrodes constructed from recordable CDs in stationary cell. ...
Carbon fiber microelectrodes for adsorptive stripping analysis of trace nucleic acids
(Elsevier B.V., 1998-01-15)
Carbon fiber ultramicroelectrodes are shown to be suitable for adsorptive stripping potentiometric measurements of trace DNA and RNA. The origin of the carbon fiber has a profound effect upon its suitability for trace ...
Fast ultrasound-assisted treatment of urine samples for chronopotentiometric stripping determination of mercury at gold film electrodes
(Elsevier B.V., 2006-06-30)
This work describes an efficient, fast, and reliable analytical methodology for mercury determination in urine samples using stripping chronopotentiometry at gold film electrodes. The samples were sonicated in the presence ...
Indirect polarographic and cathodic stripping voltammetric determination of cefaclor as an alkaline degradation product
(Elsevier B.V., 1999-11-01)
Cefaclor is not reducible at a mercury electrode, but it can be determined polarographically and by cathodic stripping voltammetry as its initial alkaline degradation product which is obtained in high yield by hydrolysis ...
Continuous production of a multi-filament reinforced metal matrix composite strip from the semisolid state
(2014-01-01)
Continuous metal matrix composite strip casting (MMCS-ing) composed of six 0.3-mm diameter annealed bare copper wires in a eutectic SnPb matrix was manufactured by a two-roll melt dragged processing (TRMD-ing) method at a ...
Electrochemical CO stripping on nanosized Pt surfaces in acid media: A review on the issue of peak multiplicity
(2018-04-15)
This manuscript reviews the complex behavior of the electrochemical oxidation of adsorbed CO (CO stripping) on Pt nanoparticles in acid media. While on low-index Pt single crystals the so-called CO stripping generally ...
Simple, direct and simultaneous stripping voltammetric determination of lead and copper in gasoline using an in situ mercury film electrode
(2014-01-01)
An improved procedure is presented to determine Pb(II) and Cu(II) in gasoline using a mercury film electrode generated in situ. The method is based on the reduction of the metal ions at adequate potentials on the glassy ...
