High-Speed Rotating Disk Electrode Unit

Review of Scientific Instruments, 1965
A rotating disk electrode assembly is described for interchangeable electrodes of 1–1000 mm2 exposed surface area. In aqueous solutions the speed of rotation can be varied between 50 and 40 000 rpm for the smallest, and between 50 and 5000 rpm for the largest electrode diameters. The standard deviation from the nominal value of the revolutions per unit

Rotating-Disk-Sample Electrode Method

Applied Spectroscopy, 1963
Sample rotation during excitation in metal emission spectroscopy is quite common. Rotating sample holders are available commercially. The advantages of sample rotation during excitation are: 1) More representative sampling is achieved as more of the sample surface is exposed to electrical discharge; 2) Improved spectral intensity, because a larger area

Linear scan voltammetry at rotating disk electrodes

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1986
Abstract A fast and reliable numerical method for the simulation of linear scan voltammetric (LSV) current responses of non-reversible redox reactions at the rotating disk electrode (RDE) is described. The dependence of the response on the parameters of the technique and on kinetic parameters is analysed.

Rotating ring disk electrode in molten chloride

Electrochimica Acta, 1989
Abstract A rotating ring disk electrode rrde assembly for use in molten chloride at 723 K has been constructed. The electrode is made of nickel and high purity alumina. The rotating electrode sealing is made of glass cloth. By the use of this rotating ring disk electrode, cathodic reduction of CdCl 2 in molten LiCl-KCl eutectic melt at 723 K has ...

Rotating waves on disk and ring electrodes

Journal of the Chemical Society, Faraday Transactions, 1996
Experimental studies have been carried out with cobalt disk and ring electrodes in buffered phosphate solutions under potentiostatic control with the Haber–Luggin capillary of the reference electrode placed in the centre of the electrode close to the surface.The applied potential is adjusted to be cathodic with respect to the Flade potential.

Electrohydrodynamical impedance on a rotating disk electrode

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1982
Abstract The electrohydrodynamical impedance on a rotating disk defined as the ratio of the mass-transfer rate response to a small sine-wave modulation of the angular velocity has been calculated for an Ostwald fluid. This impedance, expressed as a function of the modulation frequency suitably reduced by means of the rheological parameters, is then ...

Rotating disk electrode studies in cryolitic melts

Electrochimica Acta, 1988
Abstract A rotating disk electrode assembly for use in cryolitic melts at 1020° K is described. The electrodes press-fitted into a boron nitride insulation are made of tungsten plated with gold or of titanium diboride. The performance of the rotating disk system is tested by measuring limiting currents for Mn2+ reduction on gold at rotation rates up ...

Hydrodynamically modulated rotating disk electrodes

1985
Hydrodynamically modulated rotating disk electrodes (HMRDE) have been studied and utilized with a basic system. Experimental results follow the theoretical predictions fairly closely with a few exceptions. HMRDE is useful in reducing complications due to background currents.
