Basic Info

What is Potassium Iodate?

Potassium iodate, chemical formula KIO3, is often added to table salt (sodium chloride, NaCl), that is, iodized table salt, which is used to supplement iodine components and prevent iodine deficiency diseases. Potassium iodate is soluble in water and dilute sulfuric acid, but insoluble in ethanol. It is colorless when dissolved in water.

Iodine is one of the important trace elements in the human body, and is the main raw material for the synthesis of thyroid hormones and the regulation of thyroid growth and secretion. Potassium iodate (KIO3) is an iodine fortifier with more stable chemical properties and longer shelf life than potassium iodide, and has been widely added to edible salt to correct iodine deficiency. Studies have shown that excessive iodine intake is an independent risk factor for thyroid cancer. The potential role of KIO3 in cancer has also been reported accordingly. Multiple previous studies have shown that injection of KIO3 can inhibit the growth rate and size of ovarian tumors and spindle cell sarcoma in animal models, suggesting that KIO3 may serve as a new means of treating cancer. Different concentrations of KIO3 have effects on the proliferation, cycle and regulation of related genes in thyroid squamous cell carcinoma SW579 cells.

Potassium Iodate Uses

Wheat flour treatment agent; dough modifier; nutrition enhancer.

Prepare potassium carbonate conventional solution. Evaluation of zinc, iodine, arsenic. Used as an oxidizing representative in volumetric analysis.

Made use of as livestock feed additive. In medication, it is made use of as iodized salt or medication for the prevention and also treatment of native goiter.

Application of Potassium Iodate

Potassium iodate is occasionally utilized to iodize common salt to stop iodine deficiency. Due to the fact that iodide can be oxidized to iodine by molecular oxygen under wet conditions, the American firm adds thiosulfate or various other antioxidants to potassium iodide. In other nations, potassium iodate is used as a source of dietary iodine. It is also a component of some infant formula.

Like potassium bromate, potassium iodate is sometimes used as a curing agent in cooking.

Preparation of Potassium Iodate

The commercial prep work methods of potassium iodate include potassium chlorate oxidation, focused nitric acid oxidation, hydrogen peroxide oxidation as well as electrolysis. Potassium chlorate oxidation approach as well as concentrated nitric acid oxidation approach produce a huge amount of hazardous gas chlorine and also nitrogen dioxide, and due to the volatilization of iodine brought on by home heating reaction, the conversion rate of iodine is low. The hydrogen peroxide in fact consumed by the hydrogen peroxide oxidation approach is twice the theoretical amount, and the price is relatively high. The electrolysis approach requires to add dichromic acid to reduce the existing effectiveness and reduce side reactions. The product has even more pollutants and also chromium air pollution. The electrolysis method has higher needs for the ion membrane layer, intricate equipment, as well as greater manufacturing costs.

The preparation approach of potassium iodate makes use of the oxidation performance of chlorine gas to oxidize potassium iodide to form potassium iodate in a weakly alkaline tool. The pH worth of the reaction system is regulated between 7-10 as well as the temperature level is 60-100 ° C. After the response is finished, utilize Concentrated hydrochloric acid assists in the seclusion of the product. The method of the present creation is easy and also risk-free to run, low in tools requirements, high in item pureness, as well as the three wastes are very little, as well as appropriates for large-scale industrialized clean manufacturing. The application price of iodine is high, and potassium chloride is supplied as a spin-off. High commercial returns.
