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。

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

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
