What is Potassium Iodide Solution?

Potassium Iodide Solution As a part of thyroxine, iodine is carefully pertaining to the basal metabolism of animals as well as poultry, as well as takes part in mostly all material metabolic process processes. Iodine shortage in livestock will certainly cause thyroid hypertrophy, decrease basic metabolic price, as well as affect growth and growth. Young animals and animals and fowl feeds in iodine-deficient locations require to be iodized. High-yielding dairy cows and also high-yielding laying chickens need iodine to increase their iodine needs. The iodine in milk and also eggs boosts with the increase of feed iodine. High-iodine eggs have actually been reported to lower cholesterol levels in the human body and also are beneficial to the wellness of individuals with high blood pressure. In addition, throughout the animal fattening period, although there is no iodine shortage, in order to make the thyroid feature of livestock as well as poultry energetic, enhance the anti-stress ability, and keep the highest manufacturing ability, iodide is additionally supplemented, as well as potassium iodide is included in the feed as an iodine resource to stop iodine deficiency., to advertise growth, increase egg production price as well as reproduction rate as well as boost feed application rate, the enhancement amount in the feed is typically numerous PPM, due to the fact that it is unpredictable, usually include ferric citrate and calcium stearate (typically include 10%) as a safety representative to support.

Potassium Iodide Solution is used as an iodine supplement in the form of tablets, mixtures and oral liquids. In recent years, the clinical application of Potassium Iodide Solution has been continuously expanded, and it has been widely used in the treatment of diseases such as dermatology, ophthalmology, arthritis, lead-induced nephropathy and breast hyperplasia, with satisfactory results. Since potassium and sodium are in the same main group and have very similar properties, it is difficult to separate the impurity sodium ions in potassium iodide. The traditional purification method of potassium iodide is repeated recrystallization with water to achieve the purpose of purification. The solubility of Potassium Iodide Solution and sodium iodide in water is very large, so the method of recrystallization with water to purify potassium iodide has a low yield, about 80%, and the effect of removing sodium is not ideal.

Potassium Iodide Solution Uses

  1. Potassium Iodide Service is often used as a logical reagent, and also is additionally utilized in the preparation of photo photosensitive emulsifiers as well as in the pharmaceutical market.
  2. Potassium Iodide Remedy is made use of in photosensitive emulsion, soap, lithography, organic synthesis, medication, artificial additive, etc.
  3. otassium Iodide Remedy is an allowed food iodine fortifier. my nation specifies that it can be used in baby food, and the dose is 0.3-0.6 mg/kg. It can additionally be used for table salt, and the use quantity is 30-70mL/ kg. As a part of thyroxine, iodine participates in the metabolic process of all compounds in livestock and chicken as well as maintains warm balance in the body. It is an essential hormone for the development and also recreation of animals and poultry for lactation. It can boost the growth performance of livestock and poultry and advertise the wellness of the body. If the body of livestock and also poultry lacks iodine, it will certainly result in metabolic problem, body problem, goiter, influence nerve feature, fur color and feed food digestion as well as absorption, as well as ultimately cause slow down development and also development.
  4. potassium Iodide Remedy is utilized in dietary supplements (iodine fortifiers). The amount of common salt is less than 0.01%.
  5. Potassium Iodide Option is used as analytical reagent, chromatography as well as area analysis.

Potassium Lodide Solution Production Method

1. For the formic acid reduction method, see potassium iodide, the difference is that arsenic and heavy metal removal agents are added for solution purification. Iron filings reduction method Add 100% to 103% of the theoretical amount of caustic potash to a reactor filled with distilled water, add a certain amount of iodine in stages under stirring, and keep stirring at 80 to 90 °C for about 1 hour. The reaction solution is brown. When the Ph value is 6 to 7, potassium iodate crystals appear. The reaction solution was cooled to below 30°C, and iron filings were added to reduce potassium iodate to potassium iodide. The reaction starts violently. After the reaction is moderated, heat and boil, continue to stir the reaction for 1 to 2 hours, then adjust the Ph value to 8 with 10% caustic potash solution, add arsenic remover and heavy metal remover to purify the solution, stand, filter, remove Arsenic and heavy metals and other impurities, the filtrate is evaporated and concentrated to precipitate crystals, and then crystallized by cooling, centrifuged, and dried to obtain the finished product of edible Potassium Iodide Solution, which is 3I2+6KOH→5KI+K1O3+3H2OKIO3+3Fe+3H2O→KI+3Fe(OH) 2
2. At present, Potassium Iodide Solution is mostly produced by the formic acid reduction method in China. That is, Potassium Iodide Solution and potassium iodate are generated by the action of iodine and potassium hydroxide, and then potassium iodate is obtained by reducing Potassium Iodide Solution with formic acid or charcoal. However, iodate is generated in this method, and the product should not be used as a food additive. Food grade Potassium Iodide Solution can be produced by the iron filing method. The iron filing method uses iodine and iron filings as raw materials. A part of iron filings was placed in the reactor, 7 parts (mass) of water was added, and 3.3 parts of iodine was added in batches at 65~cT (high temperature iodine is easy to sublime). After adding iodine tablets, the solution is dark reddish-brown, and the second batch of iodine tablets can be added only after the solution is light green. Then the iron filings are filtered off to obtain a ferrous iodide solution, which is added to a 10:3 (mass) potassium carbonate aqueous solution to generate iron carbonate precipitation and Potassium Iodide Solution. The solution is allowed to stand, and the supernatant liquid is precipitated after clarification, heated and concentrated to a relative density of 1.75-1.81 and then filtered; when the filtrate continues to evaporate to a relative density of 1.93-1.98, it is filtered while hot. Cool to 60~70℃ and stand for crystallization, and after separation, dry at 70~90℃ to obtain anhydrous Potassium Iodide Solution product. Fe+I2→FeI2FeI2+K2CO3—2KI+FeCO3↓

Precautions for Potassium Iodide Solution

1. Drinking a lot of water and increasing the consumption of salt can both increase the excretion of iodine.

2. Those with a history of allergy to iodine are prohibited.

3. Concentrated iodine solution can cause swelling and tenderness of salivary glands, burning sensation in the mouth and throat, metallic taste, pain in teeth and gums, and increased saliva secretion.

4. Use this product as an expectorant, only for chronic respiratory tract inflammation. The dose should be small and the course of treatment should be short. It is not suitable for young people to avoid or aggravate acne or affect thyroid function.

5. It is forbidden for pregnant and lactating women; the use of iodine in infants and young children can easily cause skin rashes and affect thyroid function, so it should be disabled; patients with oral diseases, acute bronchitis, tuberculosis, hyperkalemia, hyperthyroidism, impaired renal function use with caution.
