说明

General description

KIO ₃ 可作为 KI 的替代物用于辐射防护。KIO ₃ 的 γ 热降解动力学研究-射线显示，辐照后分解速率增加，而活化能降低。

Application

碘酸钾 (KIO ₃) 可作为氧化剂用于估计植物样品中的可水解丹宁（没食子单宁和鞣花酸单宁）。也可用于制备聚苯胺、聚（ o -茴香胺）、聚 [ 苯胺-共-（ o -茴香胺）和 TiO ₂ 纳米颗粒。

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
