General description

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.

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.
