1. It is used for the determination of trace components of tellurium and niobium and the preparation of developer, as well as other reducing agents; 同题参见

2. Lignin can be used as a stabilizer for man-made fibers, bleaching agents for fabrics, photographic developers, bleaching and dyeing deoxidizers, dyes and spices as reducing agents, lignin can be used as papermaking agents, etc. 更多阅读

3、Industrial grade sodium bisulfiteUsed as a common teaching method to analyze and study the main reagents and photosensitive resistance materials;

4. Reduced bleach has a bleaching effect on food and has a strong inhibitory effect on oxidase in plant food. According to the current laws and regulations of our country, it can be used for many candied fruits, and the actual control usage for great work is 2.0 g/kg. It can also be used to detect standard glucose, liquid environment and develop canned food, grape and blackcurrant juice through the production of glucose, sugar, crystal sugar, caramel, candy, bamboo shoots, mushrooms and mushroom products. The usage of great information resources is 0.60 g/kg. Residues of bamboo shoots, shiitake mushrooms, canned mushrooms, preserved fruits, grapes and blackcurrant juice concentrate (SO2) ≤ 0.05 g/kg; Residues of potato starch ≤ 0.03 g/kg; Residues of biscuits, sugar and vermicelli should be less than 0.1 grams per kilogram, while residues of liquid glucose should not exceed 0.2 grams per kilogram.

5、Industrial grade sodium bisulfiteIn the printing and dyeing technology enterprises in the development of industry as a deoxidizer and bleaching agent, for students to analyze a variety of cotton fabric scouring, can prevent cotton fiber for a local oxidation and influence factors to study the strength of fiber materials, improve the whiteness of scouring products. The photosensitive industry is used as a developer. Used as a reducing agent in the organic industry to produce, 2,5-dichloropyrazolone, anthraquinone -1-sulfonic acid, 1-aminoanthraquinone, sodium aminosalicylate, etc., to prevent the production of semi-finished products during the production process. reaction to a process. Oxidation. Paper industry can be used as lignin removal agent. The textile industry can be used as a stabilizer for man-made fibers. The electronics industry is used to make photoresistors. Water treatment technology industry is mainly used for electroplating wastewater and drinking water treatment;

6. Used as a bleaching agent, preservative, filler and antioxidant in the food industry. Also used for the synthesis of therapeutic drugs, used as a reducing agent in the production of dehydrated vegetable products;

7. Industrial grade sodium bisulfite is used to produce sulfite cellulose, sodium thiosulfate, organic chemicals, bleached fabrics, etc. It can also be used as a reducing agent, a preservative, a dechlorinating agent, etc.

8、Industrial grade sodium bisulfiteThe laboratory can be used to study the preparation of sulfur dioxide.
