TLDR
In this article, the authors studied an estuary to determine the distribution of iodine species as a function of salinity, and examined the results for evidence of interconversion of species in the estuary.Abstract:
IODINE in seawater is present as iodate (IO3−) and as iodide (I−)1–3. Although there is some uncertainty in the true redox potentials of natural waters4, the thermodynamically stable species of iodine in seawater, and in river waters which are well oxygenated, is iodate5–7. We have studied an estuary to determine the distribution of iodine species as a function of salinity, and examined the results for evidence of interconversion of species in the estuary. We report here that iodide is the dominant form in river water and is oxidised to the thermodynamically stable iodate in the sea, not in the estuary.read more

The geochemistry of iodine - a review.
TL;DR: Consideration of the geochemical cycle of iodine reveals that its transfer from the oceans to the atmosphere is probably the most important process in its geochemistry.

TL;DR: Iodine was discovered as a novel element in 1811 during the Napoleonic Wars and to celebrate the bicentennial anniversary of this event the history and many facets of iodine research that have evolved since its discovery are reflected on.

Application of portland cement-based materials to radioactive waste immobilization
M. Atkins,Fredrik P. Glasser +1 more
TL;DR: In this paper, it is shown that Portland cements are very similar worldwide but supplementary materials such as fly ash and slag are less well-specified and the main immobilizing potential of cement systems comes from their high internal pH allowing precipitation of many nuclides as hydroxides.

Iodine dynamics in soils
TL;DR: In this paper, the transformation and reaction kinetics of iodide and iodate added to soil in relation to soil properties were investigated, using solid phase fractionation coupled with solution phase speciation (HPLC-ICPMS).

TL;DR: In this article, the authors provide a thorough, up-to-date coverage of controls on the chemical quality of surface and ocean waters. But they do not provide a detailed analysis of the results of their experiments.

Iodine in inshore and off-shore marine waters
TL;DR: In this paper, the temporal variation of iodate and total iodate in the Menai Straits and Irish Sea is discussed together with station data for the Atlantic Ocean, and it is suggested that the low iodate concentrations of tropical surface waters are more likely to have a biological origin.

‘Reactive’ and ‘unreactive’ iodine in seawater — A possible indication of an organically bound iodine fraction
TL;DR: An iodine component in seawater, which is "unreactive" to the total inorganic method described by Truesdale and Spencer (1974), has been discovered as mentioned in this paper.

The total Iodine and Iodate-iodine content of sea-water☆
TL;DR: Iodine in sea water samples from the Northeast Pacific and Arctic Oceans was determined by two independent methods of analysis, one of which was also capable of determining iodate.
