use

1. Potassium iodide is often used as a synergist for steel pickling corrosion inhibitors or other corrosion inhibitors. Potassium iodide is the raw material for preparing iodide and dyes. It is used as a photographic emulsifier, food additive, as an expectorant, diuretic in medicine, as a preoperative drug for the prevention and treatment of goiter and hyperthyroidism, and also as an analytical reagent. Used in the photographic industry as a photosensitive emulsifier, and also as a medicine and food additive.

2. The food industry is used as a nutritional supplement (iodine fortifier). It can also be used as a feed additive.

3. Used as analytical reagent, such as preparing iodine standard solution as auxiliary reagent. It is also used as a photosensitive emulsifier and feed additive. Used in the pharmaceutical industry.

4. Potassium iodide is a co-solvent for iodine and some insoluble metal iodides.

5. The so-called iodized edible salt we often eat is to add potassium iodide or potassium iodate (in a ratio of one part in 20,000) to ordinary table salt (pure sodium chloride).

6. Used in medicine to prevent and treat endemic goiter, promote the absorption of ocular vitreous opacity and expectorant. It can also be used as analytical reagent, chromatography analysis and point pain analysis.
