Square wave voltammetry at the dropping mercury electrode: Experimental
TLDR
In this paper, a trace analysis using square wave voltammetry at the dme is presented, which is shown to have the same order of sensitivity as differential pulse polarography but is much faster to perform.Abstract:
: Experimental verification of earlier theoretical work for square wave voltammetry at the dropping mercury electrode is given. Experiments using ferric oxalate and cadmium (II) in HC1 confirm excellent agreement with theory. Experimental peak heights and peak widths are found to be within 2% of calculated results. An example of trace analysis using square wave voltammetry at the dme is presented. The technique is shown to have the same order of sensitivity as differential pulse polarography but is much faster to perform. A detection limit for cadmium in 0.1 M HC1 for the system used here was 7 x 10 to the minus 8th power M.read more

Adsorption effects in square-wave voltammetry of totally irreversible redox reactions
TL;DR: In this article, the influence of reactant adsorption on square-wave voltammograms of totally irreversible redox reactions is analyzed theoretically, and the properties of the response ip, Ep and ΔEp/2 are expressed by the equations 6, 7 and 8, respectively.

Square wave polarography and some related techniques
TL;DR: The theory of square wave polarography is reviewed, and methods for obtaining increased sensitivity in A.C. polarography are outlined, including a new technique which makes use of an amplitude-modulated radio-frequency polarizing current as discussed by the authors.

Direct current effects in pulse polarography at the dropping mercury electrode
TL;DR: In this paper, extensive computer simulations of differential pulse polarograms indicate that the background is due to double layer effects and the relative signal above background is maximized by long drop times and intermediate pulse amplitudes.

TL;DR: In this article, the authors pointed out that de Galan is guilty of the charge he has made against Willis and west(1), i.e., he has failed to consult all of the pertinent literature.
