Potassium iodide is used in the manufacture of iodides and dyes. It is used as a photographic emulsifier. In medicine, it is used as expectorant, diuretic, goitre preventive agent and pre-surgical drug for hyperthyroidism, and also used in the manufacture of rheumatism and pain relief cream with pain-relieving and blood activating effects. It is the co-solvent of iodine and some insoluble metal iodides. Used as livestock feed additives.

Uses of Potassium iodide.

Potassium iodide is permitted to use food iodine fortification agent, China's regulations can be used for baby food, the use of 0.3-0.6mg/kg. can also be used for salt, the use of 30-70mL/kg. iodine as a component of thyroxine, involved in the metabolism of all substances in livestock and poultry and maintain the body's thermal balance of the growth of livestock and poultry, reproduction of lactation of the indispensable hormones, can improve the growth of livestock and poultry, promote the health of the body. It can improve the growth performance of livestock and poultry and promote the health of the body.

If the body of livestock and poultry iodine deficiency, will lead to metabolic disorders, body disorders, goiter, affecting nerve function and fur colour and feed digestion and absorption, ultimately leading to slow growth and development.

Preparation of Potassium iodide.

Product Method of Bulk Potassium iodide Powder.

Formic acid reduction method will be industrial grade iodine tablets added to the reactor with stirring, add water, and slowly add potassium hydroxide solution with a relative density of about 1.3 under stirring to make the reaction complete. The reaction solution is purple-brown, Ph value is 5-6, some potassium iodate crystals appear in the container. Formic acid was slowly added to the solution to reduce the potassium iodate.

The solution after reduction by formic acid and then add caustic potash, adjust the Ph value of 9 ~ 10. Passed into the steam, holding 1 ~ 2 h. Static, filtration to remove insoluble material, get clear filtrate, concentrated by evaporation until most of the crystals precipitated, and then cooled crystals, centrifugal separation, the crystals will be dried at 110 ° C, to produce potassium iodide finished products. Its 6KOH+3I2→5KI+KIO3+3H2OK103+3HCOOH→KI+3H2O+3CO2↑
