Potassium iodate Usage

1. Salt iodisation in the food industry: Potassium iodate is commonly used for salt iodisation to prevent iodine deficiency disorders such as goitre. Compared with potassium iodide, potassium iodate is more stable and not easy to decompose under humid conditions, so it is more suitable for salt iodisation.
2. Use as a pharmaceutical preparation in medicine: Potassium iodate is used in certain pharmaceutical preparations, mainly as a disinfectant and antibacterial agent. It is also used in the treatment of some iodine deficiency-related diseases.
Diagnostic reagents: Potassium iodate is also used in certain medical tests and diagnostic reagents.
3. Used as a standard solution in chemical analyses: In chemical analyses, potassium iodate can be used as a standard solution for titrimetric analyses, especially in redox reactions.
Oxidising agent: It is often used as an oxidising agent, participating in various oxidation reactions.
4. Used as dyes and pigments in industrial applications: Potassium iodate is used in the manufacture of dyes and pigments and plays an important role in the colouring process.
Pyrotechnics: Potassium iodate is an important oxidising agent component in the manufacture of pyrotechnics, providing oxygen to maintain combustion.
Electronic industry: It is used in the manufacture of certain electronic products.
5. as an experimental reagent in laboratory applications: Potassium iodate is used in the laboratory as a reagent in a variety of chemical reactions, particularly in the study of redox reactions and in analytical chemistry.
6. As a disinfectant in water treatment: Potassium iodate can be used as a disinfectant in water treatment to help destroy germs and microorganisms in water.
7. Use as a fertiliser in agriculture: In agriculture, potassium iodate is used as a component of certain fertilisers to replenish the iodine content of the soil and to promote plant growth.
