Iron(III)-carboxylate photochemistry induces iodate reduction
2022<p>Aerosols and clouds are complex systems containing organic and inorganic species, which play central roles in atmospheric chemistry and physics, climate, air pollution and public health. Particularly chemical reactions which occur in the aqueous phase can change the composition and oxidizing capacity of the troposphere via the ...

The successive reduction of iodate to iodide driven by iron redox cycling
Journal of Hazardous MaterialsFerrous iron (Fe(II)) produced by microbial Fe(III) reduction and reactive oxygen species (ROS) generated from aerobic Fe(II) oxidation can mediate iodate (IO3-) reduction and iodide (I-) oxidation, respectively. Nevertheless, how Fe redox cycling under redox fluctuating conditions drives transformation of iodine species remain unclear.

A new bifunctional electrochemical sensor for oxidation of cysteine and reduction of iodate
Journal of Electroanalytical Chemistry, 2013Abstract In this work, a new organic–inorganic hybrid compound containing N,N′-bis(salicylidene)-1,2-phenylenediaminocobalt (III) (CoSal) complex and a Keggin type polyoxometalate, H 4 SiW 12 O 40 (SiW 12 ), has been synthesized and characterized.

On the reduction of iodate in Briggs–Rauscher type chemical oscillators
J. Chem. Soc., Chem. Commun., 1984Oxidation of organic compounds in the presence of iodate ion is significant to the behaviour of the Briggs–Rauscher oscillating system; a new induced reaction in which iodine is liberated from iodate during the oxidadion of oxalic acid by a one electron oxidant is described.

Electrochemical reduction and flow detection of iodate on (Bu4N)2Mo6O19 self-assembled monolayer
Analytical and Bioanalytical Chemistry, 2005A stable monolayer of the inorganic-organic hybrid polyoxometalate (Bu4N)2Mo6O19, denoted as Mo6O19, was formed on a sodium-3-mercapto-1-propanesulfonate (MPPS)-covered gold electrode surface, interlaced with an anionic poly(dimethyldiallylammonium chloride) (PDDA) binding layer based on the electrostatic self-assembled (ESA) technique.

Chaos during the Reduction of Iodate in Alkaline Solution: Geometrical Effect of the Electrode
The Journal of Physical Chemistry B, 1998Geometrical effects on the oscillatory behavior during the reduction of iodate in an alkaline solution have been studied in detail. We have found that the geometrical factors greatly affect the oscillatory behavior when the iodate concentration is smaller, and chaos appears on the electrodes with smaller size or smoother surface, whereas at higher ...

New insight into the potential oscillations during iodate reduction in alkaline solution
Journal of the Chemical Society, Faraday Transactions, 1997Potential oscillations during the reduction of iodate ions in alkaline solution under galvanostatic conditions have been re-investigated without adding iodide. The oscillations can take place only when the applied current is larger than the limiting current, and the oscillation amplitudes are within the plateau region of the limiting current.

Study of acid and reductant functions of hydrazine sulphate by iodate-iodide mixture
Fresenius' Zeitschrift f�r Analytische Chemie, 1957Hydrazine sulphate was found to liberate two atoms of iodine per molecule, when treated with an excess of iodate and iodide, and this was determined by thiosulphate or arsenious oxide in borax-boric acid buffer. The study of the action of iodate-iodide mixture on hydrazine sulphate at different stages of neutralisation and decomposition was carried out

Marine aerosol is highly enriched in iodine, mostly in the form of iodate (IO(3)(-)) ions, compared to its relative abundance in seawater. This paper describes a laboratory study of the photochemical reduction of IO(3)(-) in the presence of humic acid.

The iodate reduction by hydrogen peroxide in acidic solutions is part of the Bray-Liebhafsky and Briggs-Rauscher oscillating reactions. At low hydrogen peroxide concentrations, typical of the Bray-Liebhafsky reaction, its rate law is -d[IO(-)(3)]/dt = (k'(R) + k"(R)[H(+)])[IO(-)(3)][H(2)O(2)] with k'(R) = 1.3 × 10(-7)(20°), 7.8 × 10(-7) (39°), 1.4 × 10(
