Sodium Meta Bi Sulfite / Sodium Metabisulfite

Sodium Meta Bi Sulfite / Sodium Metabisulfite

We are a trusted supplier and exporter of Sodium Metabisulfite, known for its high purity, consistent quality, and excellent performance in various industrial applications. Our Sodium Metabisulfite (Na2S2O5) is widely used as a reducing agent, preservative, antioxidant, and disinfectant across industries such as water treatment, food processing, textiles, leather, and chemical manufacturing.

Sodium Metabisulfite is a white to slightly yellowish crystalline powder with a characteristic sulfur dioxide odor. It is highly soluble in water and releases sulfur dioxide (SO2), making it effective for sterilization, dechlorination, and purification processes. Its strong reducing and sulfonating properties make it suitable for a wide range of industrial and commercial applications.

Application of Sodium Metabisulfite:

  • 1. Used in chemical processing to purify or isolate aldehydes and ketones by forming bisulfite compounds.
  • 2. Acts as a reducing and sulfonating agent in various industrial processes.
  • 3. Functions as an oxygen scavenger to remove dissolved oxygen in wastewater treatment and pipelines.
  • 4. Serves as a bleaching agent in paper pulp, cotton, wool, and clay processing.
  • 5. Used as a preservative and antioxidant in food and beverage industries and as a hair treatment agent.
  • 6. Widely applied in leather processing, textile industry, gas purification, and water treatment.
  • 7. Used as a reducing agent in chemical manufacturing industries.
  • 8. Acts as an alternative to sulfur dioxide for equipment sterilization.
