Potassium Iodate manufacturer, supplier and exporter. Potassium Iodate is an oxidizing agent. Potassium Iodate used primarily as a stable source of Iodine, which is liberated in the presence of Iodide ion and acid, in the titration of Thiosulfate and Sulfite solutions.
Technical Bulletin
Description :
Potassium Iodate occurs as a white, crystalline powder. KIO3 can be used as a substitute of KI in radiation protection.A kinetic study of thermal degradation of KIO3 by γ-rays suggests that rate of decomposition increases while activation energy decreases upon irradiation.
Formula : KIO3 Molecular Wt. : 213.9927
Application :
Potassium Iodate (KIO3) may be used as an oxidizing agent in the estimation of hydrolyzable tannins (gallotannins and ellagitannins) in plant samples. It may also be used in the preparation of polyaniline,poly(o-anisidine),poly[aniline-co-(o-anisidine) and TiO2 nanoparticles.Iodization of edible salt.
