Description
Sodium Metabisulphite (Na₂S₂O₅) is a versatile reducing agent widely used in gold mining, water treatment, food and beverage processing, chemical manufacturing, and various industrial applications. It is particularly valued for its ability to remove residual chlorine, control oxidation, and provide sulphur dioxide in controlled processing
environments.
Major Uses & Applications
- Gold mining: used as a reducing agent, particularly in processes involving the treatment of gold-bearing solutions.
- Water treatment: used to remove residual chlorine and other oxidizing agents from water.
- Food & beverage processing: used as a preservative and antioxidant in approved food-grade applications.
- Chemical manufacturing: used as a reducing agent and source of sulphur dioxide in various chemical processes.
- Pulp & paper: used in selected bleaching and processing applications.
- Textile industry: used in certain dyeing and bleaching processes.
- Industrial processing: used where reducing, dechlorinating, or preservative properties are required.
