说明

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.

Potassium iodate assisted synthesis of titanium dioxide nanoparticles with superior water-dispersibility.

Yawen Wang et al.

Journal of colloid and interface science, 430, 31-39 (2014-07-07)

In this paper, we report a novel polyol process to synthesize highly water-dispersible anatase titanium dioxide (TiO2) nanoparticles (∼5 nm) by the introduction of inorganic oxidizing agent--KIO3. The obtained TiO2 nanoparticles are well dispersible in water at pH≥5.0 and the
