TLDR
In this article, the deposition stripping behavior of iodide films at the hanging mercury drop electrode (HMDE) was investigated, and the surface monolayers of Hg. HgI and Hg/sub 2/I/sub 3/2/sub 4/1/2.Abstract:
The deposition-stripping behavior of iodide films at the hanging mercury drop electrode (HMDE) is investigated. Surface monolayers of Hg . HgI and Hg/sub 2/I/sub 2/ are postulated based on the percentage occupancy of the available sites at the surface of the HMDE. Submonolayer films of Hg . HgI, as stripped from the electrode, are used to determine iodine concentrations from 1 to 50 ppb with a standard deviation of 0.3 ppb.read more

Direct determination of iodide in seawater by cathodic stripping square wave voltammetry
TL;DR: In this paper, a procedure for direct determination of iodide in sea water is described, using cathodic stripping square wave voltammetry, which is more sensitive than previous methods by 1-2 orders of magnitude.

Cathodic stripping voltammetry: Part I. Determination of organic sulfur compounds, flavins and porphyrins at the sub-micromolar level
TL;DR: In this article, the experimental parameters of cathodic stripping voltammetry have been studied and optimised, and the use of a cell with a mercury pool electrode has been proposed, which is valuable for the determination of several classes of organic compounds, including thiols, disulfides, flavins, flavones, pterins and porphyrins.

Application of Stripping Analysis to the Determination of Iodide with Silver Microelectrodes

TL;DR: In this article, two methods of stripping the silver halide deposit from the electrode were investigated: electrolysis with constant potential and linearly varying potential, and the quantity of electricity measured in the stripping step was a direct function of the preelectrolysis time and the bulk concentration of halide.
