General description

KIO3 can be used as a substitute of KI in radiation protection.[1] A kinetic study of thermal degradation of KIO3 by γ-rays suggests that rate of decomposition increases while activation energy decreases upon irradiation.[2]

Application

Potassium iodate (KIO3) may be used as an oxidizing agent in the estimation of hydrolyzable tannins (gallotannins and ellagitannins) in plant samples.[3] It may also be used in the preparation of polyaniline,[4] poly(o-anisidine),[4] poly[aniline-co-(o-anisidine)[4] and TiO2 nanoparticles.[5]

A widely used method for analyzing hydrolyzable tannins afer reaction with KIO(3) has been modified to include a methanolysis step followed by oxidation with KIO(3). In the new method, hydrolyzable tannins (gallotannins and ellagitannins) are reacted at 85 degrees C
