Hot Selling Sodium Selenite 98% Made in China
What is sodium selenite?
Sodium selenite, vulgar white crystal or crystalline powder, white crystal, can contain five crystal waters, stable in air, can lose water in dry air, soluble in water, insoluble in ethanol. Easily weathered in dry air, highly toxic! It is extremely toxic when inhaled or swallowed, and has a cumulative hazard. One gram of oral ingestion can cause death. In case of reducing agent, elemental selenium is precipitated.

Production Process
1. Dissolve an appropriate amount of selenium dioxide in water to form a selenite solution;
2. Add sodium hydroxide to the selenite solution to adjust the pH to 7-14;
3. Add appropriate amount of additives and adsorbents;
4. After filtration and evaporation crystallization;
5. Heating, drying, crushing and screening;
6. Sodium selenite finished product
Use of sodium selenite
1. Selenium is a component of glutathione peroxidase, which maintains the function of cell membranes through oxidation and increases the production of endogenous antioxidants of lipid properties of proteins. It participates in the conversion of energy, affects metabolism, and plays an extremely important role in the emulsification and absorption of fat and the absorption of various vitamins. At the same time, it also participates in the synthesis of coenzyme A and coenzyme Q, and affects the functions of other biological enzyme systems. It affects amino acid metabolism, protein synthesis, carbohydrate metabolism, and biological oxidation. Lack of selenium in livestock and poultry will seriously affect the growth, development and reproductive function of livestock and poultry. Alkaloid test. Seed germination test. Removes green color when making glass. Glaze preparation.
2 Used as biochemical reagents, testing alkaloids, and testing seed germination. For red glass and color glaze preparation.
3. Selenium is one of the important trace elements necessary for biology. The addition of sodium selenite to the feed can improve the egg production rate, hatching rate and hatchling rate of poultry, and treat exudative diathesis, muscular dystrophy and pancreatic nutritional atrophy. For livestock, it can improve the utilization rate of various nutrients, treat acute hemorrhagic liver necrosis, leukemia, mulberry heart disease, acute circulatory disorder, etc., and can also improve reproductive capacity. For fish, it can prevent white muscle disease, reduce mortality, and promote growth and development.
The effect of sodium selenite in feed
1. Eliminate free radicals in the body, eliminate toxins in animals, prevent blood clots, remove cholesterol, improve immunity, and improve the ability of animals to resist stress;
2. Improve the sperm activity of breeding stock, improve the quality of sperm, improve the conception rate of dams and the birth weight of piglets, improve the reproductive capacity of livestock and poultry, and prolong the service life of livestock and poultry;
3. It can promote the growth of livestock, poultry and aquatic animals, and improve carcass quality and meat quality;
4. Selenium is combined with heavy metals in physical energy, which can resist the poisoning of cadmium, lead, mercury and other metals to animal kidneys, gonads and nervous system, and form metal selenoproteins with heavy metals to detoxify and detoxify;
Features:
1. As a selenium fortifier, sodium selenite works together with vitamin E to increase the activity of glutathione peroxidase and promote the body's antioxidant capacity and immunity;
2. It can promote the formation of antibodies, maintain the stability of the internal environment in the body, and also play an important role in enhancing the body's anti-stress ability and anti-inflammatory ability;
3. Participate in the synthesis of coenzyme A and coenzyme Q, and have an impact on protein synthesis, glucose metabolism, and biological oxidation;
4. Selenium is an essential trace element for livestock and poultry, and has been widely used in feed and food.
