Beschreibung

Allgemeine Beschreibung

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.

Anwendung

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.
