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.

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.

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.

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

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 ...

FAD-modified SiO2/ZrO2/C ceramic electrode for electrocatalytic reduction of bromate and iodate
Journal of Solid State Electrochemistry, 2008SiO2/ZrO2/C carbon ceramic material with composition (in wt%) SiO2 = 50, ZrO2 = 20, and C = 30 was prepared by the sol–gel-processing method. A high-resolution transmission electron microscopy image showed that ZrO2 and the graphite particles are well dispersed inside the matrix.

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.

Potentiodynamic and potentiostatic polarization, and the rotating disk electrode technique were used to study the reduction characteristics of iodate (IO3−) ion on copper (Cu). Depending on the relative concentrations of IO3− and H+ two pH regimes were observed.

Millicoulometric determination of n-values in the polarographic reduction of cadmium and iodate ions
Journal of Electroanalytical Chemistry (1959), 1965Abstract Apparatus and procedural criteria are described which make millicoulometry an accurate and reliable technique. A micro-cell is described which permits the complete, exclusion of oxygen and causes half the initial moles of electroactive species in a 100-λ volume to be electrolyzed in 30–60 min.
