Potassium iodide is often used as a synergist for steel pickling corrosion inhibitors or other corrosion inhibitors. Potassium iodide is a raw material for the preparation of iodides and dyes. It is used as a photographic emulsifier, a food additive, as a sputum, a diuretic, a goiter prevention and a thyroid hyperfunction surgery, and as an analytical reagent. It is used as a photographic emulsifier in the photographic industry and also as a pharmaceutical and food additive.
2. Used as a feed additive. As a component of thyroxine, iodine participates in the metabolism of all substances in livestock and maintains the heat balance in the body. Iodine is an essential hormone for the growth, reproduction and lactation of livestock and poultry. It can improve the growth performance of livestock and poultry and promote the health of the body. If the body of the livestock is deficient in iodine, it will lead to metabolic disorders, disorders of the body, thyroid enlargement, affecting nerve function and the coloration of the coat and the digestion and absorption of the feed, eventually leading to slow growth.
3. The food industry is used as a nutritional supplement (iodine enhancer). Can also be used as a feed additive.
4. Used as an analytical reagent, such as preparing an iodine standard solution as an auxiliary reagent. Also used as a photosensitive emulsifier, feed additive. Used in the pharmaceutical industry.
5. Potassium iodide is a co-solvent for iodine and certain poorly soluble metal iodides.
6. Potassium iodide has two main applications in surface treatment: one is for chemical analysis, the medium reduction of iodide ion and some oxidative ion reaction are used to generate elemental iodine, and then the iodine is determined to calculate The concentration of the analyte; the second is for the complexation of certain metal ions, and its typical use is as a complexing agent for cuprous and silver in electroplated copper-silver alloys.
7. The so-called iodized edible salt that we often eat is to add potassium iodide or potassium iodat(in proportion to 20,000) to ordinary salt (pure sodium chloride).
