Sodium Dithionite
TECHNICAL SPECIFICATIONS
Sodium Dithionite, also known as Sodium Hydrosulfite, is a powerful reducing agent in white crystalline powder form. It is highly reactive and valued for its oxygen-scavenging capabilities.
This Technical Grade chemical is indispensable for stripping color and bleaching heat-sensitive materials. It is unstable in the presence of air and moisture, requiring specialized stabilization for industrial use.
In chemical processing, it acts as a primary reagent for vat dyeing and heavy metal recovery. Its rapid reaction rate makes it a preferred choice for high-speed industrial bleaching lines.
APPLICATIONS
- Textile Industry: Primarily used for vat dyeing reduction and for stripping unwanted color from fabrics
- Pulp and Paper: Employed in the bleaching of mechanical pulp and the de-inking of recycled paper.
- Water Treatment: Used to reduce hexavalent chromium to trivalent chromium in industrial wastewater.
SAFETY & RISKS
Classified as Self-Heating Substance Category 1 and Acute Toxicity 4. Must be kept dry; contact with moisture releases toxic Sulfur Dioxide gas. Wear full PPE and use dry storage.
