Uses and synthesis of Sodium bisulfite powder
Sodium bisulfite powder is also known as sodium bisulfite. Sodium bisulfite is soluble in water and the solution is acidic. Stable at room temperature, but will decompose when heated, release sulfur dioxide gas; Sodium bisulfite is a reducing agent and has antiseptic and antibacterial properties. As an intermediate in the industrial synthesis of other chemical substances; Sodium bisulfite is used in wastewater treatment to remove heavy metal ions from wastewater.
Applications/Functions of Sodium bisulfite powder
- Sodium bisulfite powder is used as a chemical deaerator and dechlorination agent for water injection treatment systems in oil fields. At present, sodium bisulfite is used as chemical deaerator in medium and low pressure boilers.
- Sodium bisulfite is the reducing bleaching agent allowed in our country. It has bleaching effect on food and strong inhibition on the oxidase in plant food.
Physicochemical Property of Sodium bisulfite powder
White or yellowish monoclinic crystals or powders with an odor of sulfur dioxide. The relative density is 1.48. In the air, it is easy to oxidize and release sulfur dioxide to form sulfate, which is easily soluble in water.
Production methodprocess of Sodium bisulfite powder
Sodium bisulfite powder was prepared by absorbing sulfur dioxide from the tail gas of acid production with soda ash solution, centrifugation and air drying at 250-300 ℃.
