Potassium iodate (K I O 3) is an ionic inorganic compound with the formula KIO3. It is a white salt that is soluble in water. [1] It can be prepared by reacting a potassium-containing base such as potassium hydroxide with iodic acid, for example: [1]

碘酸钾，化学式KIO 3，常被添加在 食盐 （氯化钠 、 Na Cl）中，即為 含碘食盐，用于补充 碘 成分，预防 碘缺乏病。 碘酸钾溶於水、稀 硫酸，不溶於 乙醇。 溶於水呈無色。 用过氧化氢和硝酸的混合溶液氧化 碘 得到 碘酸，再和 碳酸钾 反应，得到碘酸钾。 [2] 碘酸钾和 亚硫酸钠 在酸性溶液中可以发生氧化还原反应。 [3] 它在700 K（427 °C）可被金属铅还原，生成 亚碘酸钾。 [4] 它可以形成复盐，如K 2 Be (IO 3) 4 ·2H 2 O [5] 、K 2 Ni (IO 3) 4 ·2H 2 O、K 2 Zn (IO 3) 4 ·2H 2 …

2025年1月3日 · Both potassium iodate (KIO3) and potassium iodide (KI) are effective for thyroid protection in radiation exposure. The choice between them often comes down to factors like stability, availability, and regional health authority recommendations.

2022年5月17日 · Potassium iodide (KI) is the compound most commonly used to protect the thyroid gland from radioactive iodine. However, potassium iodate (KIO3) remains one of the alternative compounds, provided that the dose contains the same amount of iodine. There is no difference in shelf life between (KI) and (KIO3).

Results suggest that KIO3 is as effective a thyroid blocking agent as potassium iodide. In comparison to controls, 24-h thyroid uptake of 131I can be substantially reduced if potassium iodide or KIO3 is given to the animals within 2-4 h after exposure to 131I.

2022年3月17日 · Potassium iodide (KI) and potassium iodate (KIO3) (from pills, liquids, or powders) can help protect the thyroid gland from the effects of radioactive iodine that can occur in the air, water, and foods after a nuclear event and accumulate in …

Potassium iodate is an oxidising agent and it can cause fires when it comes into touch with flammable materials or reducing agents. The chemical formula for potassium iodate is KIO3. It can be prepared by reacting potassium bases like KOH with iodic acid.

2025年2月18日 · Iodine can be added to salt in the form of potassium iodide (KI) or potassium iodate (KIO3). Because KIO3 has higher stability in the presence of salt impurities, humidity, and porous packaging, it is the recommended form. Potassium iodate, which is formed as a secondary product, is reduced by activated carbon.
