Overview
A white to pale-yellow crystalline powder (NaHSO₃), sodium bisulfite is a versatile chemical widely used as a reducing agent, antioxidant, and preservative in industrial applications.
Key Features & Benefits
1) Powerful reducing agent used in water treatment for chlorine neutralization and in paper/textile bleaching.
2) Antioxidant and preservative in food, beverage, and pharmaceuticals, protecting against oxidation and spoilage.
3) High purity (≥58.5% SO₂ content), meeting ACS and technical grades, suitable for sensitive industrial processes.
Specifications & Packaging
Purity: ≥58.5% SO₂ assay (titration); solids form — 96–99% purity; solution form — 38–42% NaHSO₃.
Form: White crystalline powder or 40% aqueous solution (ACS grade)
Powder: 25 kg PE-lined or HDPE sacks, jumbo bulk bags
Liquid: 200 L drums or 1 MT IBCs
Applications
1) Water & wastewater treatment: Removes chlorine, neutralizes oxidants
2) Food & beverage industry: Preserves dried fruits, wines, and juices
3) Textile and paper processing: Bleaching, dye reduction, and dechlorination
4) Pharmaceutical & chemical synthesis: Used in redox reactions and as stabilizer
Usage Note
For precise dosing, perform solution-based trials: typical dosage ranges from 5 to 50 ppm depending on application. Dissolve fully and agitate consistently to maximize effectiveness.
Safety & Handling
Use dust suppression and wear gloves, goggles, and a dust mask. Store sealed in a cool, dry area, away from acids and strong oxidizers. Avoid inhalation, as it may release SO₂ gas.
