Stoichiometry of sulfite oxidation by oxygen during the determination of the volumetric mass transfer coefficient
(American Chemical Society, 2008-12)
The aim of this work was to study the effect of the initial sulfite concentration on the stoichiometric coefficient of sulfite oxidation. A combined method based on the oxidation of sulfite by oxygen in the presence of ...
ELECTROCHEMICAL METHOD FOR SULFITE DETERMINATION IN WINES BY ELECTROCHEMICAL RESPONSE USING A MEMBRANE ABSORBER SYSTEM
(SOC CHILENA QUIMICA, 2016)
This research demonstrates how the sulfite content can be measured by cyclic voltammetry using a previously reported membrane absorber system, which separates efficiently sulfite present in wine. Results obtained show ...
Electrochemical Properties of the Oxo-Manganese-Phenanthroline Complex Immobilized on Ion-Exchange Polymeric Film and Its Application as Biomimetic Sensor for Sulfite Ions
(Wiley-Blackwell, 2014-10-01)
A biomimetic sensor containing the oxo-bridged dinuclear manganese-phenanthroline complex incorporated into a cation-exchange polymeric film deposited onto glassy carbon electrode for detection of sulfite was studied. ...

Effect of some antioxidants on oxidative DNA damage induced by autoxidation of microquantities of sulfite in the presence of Ni(II)/Gly-Gly-L-His
(TAYLOR & FRANCIS LTD, 2010)
Ni(II)GGH (GGH, glycylglycyl-L-histidine) reacts rapidly with S(IV), in air-saturated solution, to produce Ni(III)GGH. A mechanism is proposed where Ni(III) oxidizes SO(3)(2-) to SO(3)(center dot-), which reacts with ...
