Reduction of iodate to iodide by cold water diatom cultures
Marine Chemistry, 2007Abstract The presence of a surface iodide maximum in seawater is commonly attributed to biological activity, however laboratory studies on the influence of phytoplankton on inorganic iodine speciation have yielded somewhat contradictory results. Here, we report changes in the speciation of inorganic dissolved iodine in nutrient-enriched seawater ...

Iodate is a strong oxidant, and some animal studies indicate that iodate intake may cause adverse effects. A key focus of the safety assessment of potassium iodate as a salt additive is determining whether iodate is safely reduced to iodide in food.To study the reduction of iodate in table salt to iodide and molecular iodine during cooking.Fifteen food

Water, Air, and Soil Pollution, 1997
The different oxidation species of iodine have markedly different sorption properties. Hence, changes in iodine redox states can greatly affect the mobility of iodine in the environment. Although a major microbial role has been suggested in the past to account for these redox changes, little has been done to elucidate the responsible microorganisms or ...

Electrochemical synthesis of WO3/PANI composite for electrocatalytic reduction of iodate
Electrochimica Acta, 2010Abstract Composite film of polyaniline (PANI) and tungsten oxide (WO3) was electrodeposited by cyclic voltammetric technique from a solution of aniline and tungstic acid. The obtained WO3/PANI film displayed a significant enhancement of electrocatalytic activity for iodate reduction and a better stability than that of pure WO3 and PANI films.

Modeling galvanostatic potential oscillations in the electrocatalytic iodate reduction system
Journal of Electroanalytical Chemistry, 1999Abstract An experimental and theoretical description of the oscillatory electrocatalytic iodate reduction system in alkaline solution is presented. Experimental measurements suggested the crucial role of a negative differential resistance as well as the presence of hydrogen evolution in the oscillatory instability.

An analytical application of the electrocatalysis of the iodate reduction at tungsten oxide films
Talanta, 2006Films of non-stoichiometric tungsten oxides have been deposited onto glassy carbon surfaces by electrodeposition from acidic W(VI) solutions and the chemical stability of these oxides was investigated by using the electrochemical quartz crystal microbalance.

Flow Injection Analysis of Iodate Reduction on PEDOT Modified Electrode
Electroanalysis, 2008AbstractPoly‐(3,4‐ethylenedioxythiophene) (PEDOT) films were electrodeposited by cyclic voltammetry on glassy carbon electrode at different anodic potentials in the range of 1.0–1.5 V (Ag/AgCl) and its electrocatalytic properties towards reduction of iodate were reported.

Temperature dependence of the transfer coefficient. The reduction of iodate in alkaline media
Journal of Electroanalytical Chemistry, 1996Abstract The reduction of iodate on a dropping mercury electrode was studied over a wide range of temperatures, and compared with earlier studies on the reduction of bromate under nearly identical conditions. A fully computerized experimental setup was used.

Abiotic and Biotic Reduction of Iodate Driven by Shewanella oneidensis MR-1
Environmental Science & Technology, 2023Iodate (IO3-) can be abiotically reduced by Fe(II) or biotically reduced by the dissimilatory Fe(III)-reducing bacterium Shewanella oneidensis (MR-1) via its DmsEFAB and MtrCAB. However, the intermediates and stoichiometry between the Fe(II) and IO3- reaction and the relative contribution of abiotic and biotic IO3- reduction by biogenic Fe(II) and MR-1

Molybdenum Catalysed Polarographic Reduction of Iodate
Analytical Letters, 1985Abstract Polarographic catalytic reduction of iodate by molybdenum (VI) is investigated in an acetate-acetic acid solution of pH 5. The catalytic wave consisted of a peak at around -1.6 V vs SCE. The effect of pH, metal ion concentration, oxidant concentration, mercury column height, surfactants and neutral salt on the wave characteristics is studied ...
