The use of potassium iodide

Use of potassium iodide

1. Potassium iodide is commonly used as a synergistic agent for iron and steel acid cleaning corrosion inhibitors or other corrosion inhibitors.Potassium iodide is the raw material for the preparation of iodide and dyes.Used as photosensitive emulsifier, food additive, expectorant, diuretic, goiter prevention and treatment and hyperthyroidism in medicine, also used as analytical reagent.Used in the photographic industry as a photosensitive emulsifier, also used in medicine, food additives.

2. Used as feed additive.Iodine, as a component of thyroxine, is involved in the metabolism of all substances in livestock and poultry and the maintenance of internal heat balance.Iodine is an essential hormone for growth, reproduction and lactation of livestock and poultry, which can improve the growth performance of livestock and poultry and promote the health of the body.If the body of livestock and poultry is lack of iodine, it will lead to metabolic disorders, body disorders, goiter, affect nerve function and by hair color and feed digestion and absorption, ultimately leading to slow growth and development.

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

4. Used as an analytical reagent, e.g. preparation of iodine standard solution as an auxiliary reagent.Also used as photosensitive emulsifier, feed additives.Used in pharmaceutical industry.

5. Potassium iodide is a co-solvent of iodine and some insoluble iodide metals.

6. Potassium iodide is mainly used in two aspects in surface treatment: first, it is used for chemical analysis. It generates elemental iodine by the medium reduction of iodide ions and some oxidizing ionic reactions.Second, it is used for complexing some metal ions. Its typical use is as complexing agent of cuprous and silver in electroplating cuprous and silver alloy.

7. The so-called iodized table salt we often eat is the addition of potassium iodide or potassium iodate to common table salt (pure sodium chloride) in a ratio of 1/20,000.

Potassium iodide has some special USES in dermatology.Its mechanism of action is partly due to its enhanced dissolution and digestion of necrotic tissue.Potassium iodide also has antifungal activity.It is used in the clinical treatment of spore filariasis, chromoblastomycosis, persistent erythema nodosa and nodular vasculitis.The use of potassium iodide should also pay attention to its side effects, it can cause pustules, blisters, erythema, eczema, urticaria, and so on, but also can make acne worse, of course, also can cause gastrointestinal reactions and mucosal symptoms.

9. Used medicinally to prevent and treat endemic goiter and promote the absorption and expectoration of vitreous opacity.It can also be used as an analytical reagent, chromatographic analysis and point pain analysis.

10. Potassium iodide can also measure the concentration of ozone and replace iodine to make starch blue. The reaction is as follows:

O3 ki + H2O + 2 = 2 koh + O2 + I2 [2]
