AGNES: a new electroanalytical technique for measuring free metal ion concentration
TL;DR: AGNES (absence of gradients and Nernstian equilibrium stripping) is a stripping technique consisting of two conceptual steps: (i) application of a potential program (e.g. a step at a fixed potential) generating a known concentration gain between the outer and inner concentrations of the metal at the mercury electrode surface together with null gradients of the concentration profiles (inside and outside the mercury electrodes) and (ii) determination of the reduced metal inside the amalgam in a stripping step as mentioned in this paper.

Gessie Brisard,Andrezej Lasia +1 more
TL;DR: In this paper, the electrochemical reaction Cd 2+ + 2 e − = CD(Hg) was studied in dimethylsulfoxide containing tetraethylammonium perchlorate as a supporting electrolyte, using dc polarography, ac admittance measurements, cyclic voltammetry with convolution and chronoamperometry.

Calculation of reversible cyclic voltammograms at spherical electrodes
TL;DR: In this article, a partly analytical formula for predicting cyclovoltammetric current at a reversible spherical electrode under conditions of mild sphericity is presented, and predictions are then made of the shapes of typical cyclic voltammograms and these are compared with experiment.

Cyclic voltammetry at microstructured electrodes
Andreas Neudeck,Lothar Dunsch +1 more
TL;DR: In this article, the theoretical treatment of cyclic voltammograms at micro-structured electrodes is presented, and a modified Randles-Sevcik equation has been derived to describe the peak current dependence for both reversible and quasi-reversible charge transfer.

Tracer diffusion of cadmium and mercury in mercury over the temperature range 283–333 K
Victor M.M. Lobo,R. Mills +1 more
TL;DR: In this paper, a set of data for trace cadmium diffusing in mercury amalgams has been produced over the temperature range 283-333 K and for zinc at 298 K. The classical open-ended capillary technique has been used for both sets of measurements.

Precise Measurement of Ionic Diffusion Coefficients with a Hanging Mercury Drop Electrode
TL;DR: In this article, the diffusion coefficient and the product of the charge number of electrode reaction n and the concentration of depolarizer c can be determined simultaneously from the time dependence of the diffusion limiting current observed at a spherical electrode of known size.
