1. What's Potassium Iodide?

Potassium iodide is an ionic compound, The iodine ion can form dark yellow precipitated silver iodide with silver ion (see photo decomposition, which can be used to make high-speed photographic film), so silver nitrate can be used to test the existence of iodine ion. Iodine, as a component of thyroxine, is closely related to the basic metabolism of livestock and poultry and participates in almost all material metabolism processes. Iodine deficiency of livestock will cause thyroid hyperplasia and hypertrophy, reduce the basic metabolic rate and affect growth and development. It is found in the feed of young livestock and livestock and poultry in iodine deficient areas Iodine needs to be added. The iodine needs of high-yield dairy cows and laying hens increase, and iodine also needs to be added to their feed. Iodine in milk and eggs increased with the increase of feed iodine chemicalbook. It is reported that high iodine eggs can reduce the content of human cholesterol and are beneficial to the health of patients with hypertension. In addition, during animal fattening, although there is no iodine deficiency, in order to make the thyroid function of livestock and poultry vigorous, enhance the anti stress ability and maintain the maximum production capacity, iodide is also supplemented. Potassium iodide is added to the feed as an iodine source, which can prevent iodine deficiency, promote growth, increase egg laying rate and reproduction rate and improve feed utilization rate. The addition amount in the feed is generally a few ppm, Because of its instability, iron citrate and calcium stearate (generally 10%) are usually added as protective agents to stabilize it.

2. Main application

It is commonly used as analytical reagent, and also used for the preparation of photosensitive emulsifier for photography, pharmaceutical industry, photosensitive emulsion, soap, lithography, organic synthesis, medicine, food additives, etc

Potassium iodide is a permitted food iodine fortifier. It can be used for table salt with a dosage of 30 ~ 70mg / kg; The dosage in infant food is 0.3 ~ 0.6mg/kg.

Potassium iodide is a food iodine enhancer allowed to be used. It can be used in infant food according to Chinese regulations, and the dosage is 0.3-0.6mg/kg. It can also be used for table salt in an amount of 30-70ml / kg. Iodine, as a component of thyroxine, participates in the metabolism of all substances of livestock and poultry and maintains the heat balance in the body. It is an essential hormone for the lactation of livestock and poultry growth and reproduction. It can improve the growth performance of livestock and poultry and promote the health of the body. If livestock and poultry are iodine deficient, it will lead to metabolic disorder, body disorder, goiter, affect nerve function, fur color and feed digestion and absorption, and finally lead to slow growth and development.

Nutritional supplements (iodine fortifiers). The consumption of table salt is less than 0.01%.

It is used as analytical reagent, chromatography and drop analysis. It is the raw material for the manufacture of iodide and dyes. Used as photographic emulsifier. In medicine, it is used as expectorant, diuretic, prevention and treatment of goiter and medicine before hyperthyroidism surgery. It is also used to manufacture rheumatic analgesic ointment with analgesic and blood activating effects. It is a cosolvent of iodine and some insoluble metal iodides. Animal feed additives are used.
