Sodium Sulphite 25kg

Sodium Sulphite Na₂SO₃ 25kg

Sodium sulfite is a versatile chemical used as an oxygen scavenger, antioxidant, and reducing agent, primarily in water treatment (dechlorinating boilers), pulp & paper (bleaching), and the food industry (preservative for dried fruits, wine). It also serves in photography (developer stabilizer), textiles (bleaching/desulfurizing), chemical manufacturing (sulfonation), and removing cyanide in gold mining.

Key Uses by Industry:
Water Treatment: Removes excess chlorine and oxygen to prevent corrosion in steam boilers and wastewater.
Pulp & Paper: Bleaches wood pulp and helps in wood fiber processing for MDF.
Food & Beverage: Preserves dried fruits, meats, and wine by preventing discoloration and microbial growth; improves dough consistency in baking.
Photography: Protects developer solutions from oxidation and helps wash fixer from emulsions.
Textiles: Acts as a bleaching, desulfurizing, and dechlorinating agent.
Chemical Manufacturing: Used in sulfonation and to produce sodium thiosulfate (hypo).
Mining: Destroys cyanide in gold processing.
