Sodium Sulfite Application:
1, In the field of water treatment
 as the deoxidant of boiler water and oilfield flooding;
 as antichlor for municipal and industrial water;
 as the raw material for the production of sodium thiosulfate;
 as the stabilizer of viscose acetal fibre;
as the bactericide of beer bottle.
2, In food industry: as bleaching agent, preservative, bulking agent, antioxidant and for the medicine synthesis
3, As analytical reagent, light dependent resistor materials and base solution of polarographic analysis
4, As antioxygen of cosmetics, mainly for hair dye cosmetics
5, As reducing agent of spice, dye and so on
6, In textile industry: as bleacher and deoxidier for fabric 
7, In paper industry: as lignin removal agent
Storage & Handling: Store the product in a cool and dry place, avoid contact sunshine ,water and moisture, avoid contact with strong acid, oxidants or poisonous substances, exposure to moisture will make it oxidze easily to sodium sulphate , not store it for a long time .
