Applications

Sodium bisulfite is widely utilized in research focused on:

  • Food Preservation: Commonly used as a preservative in the food industry, it helps prevent browning and spoilage in fruits and vegetables, ensuring longer shelf life and maintaining quality.
  • Water Treatment: Employed in municipal and industrial water treatment processes, it acts as a reducing agent to remove chlorine and chloramine, making water safer for consumption and use.
  • Pharmaceuticals: In the pharmaceutical industry, it serves as an antioxidant in drug formulations, enhancing stability and efficacy while preventing degradation of sensitive compounds.
  • Photography: Used in photographic processing, it helps in the development of film by controlling the oxidation of silver halides, leading to clearer images and improved quality.
  • Textile Industry: In textiles, it is utilized for bleaching and as a reducing agent, aiding in the production of brighter and more vibrant colors in fabrics.
