What is Sodium Metabisulfite (SMBS) and how is it used?

  • The chemical compound sodium metabisulfite has the formula Na2S2O5. Sodium pyrosulfite and sodium disulfite are two more names for it. The ionic composition Na2S2O5 is made up of the sodium cation (Na+) and the metabisulfite anion (S2O52-). Sodium metabisulfite is a white or yellowish-white powder in its natural state.
  • A residue of sodium metabisulfite is formed when a solution of NaHSO3 (sodium bisulfite) is saturated with SO2 (sulfur dioxide) and then allowed to evaporate.
  • This substance has a slightly unpleasant odor that is comparable to sulfur dioxide. It's crucial to remember that sulfite-sensitive people may experience allergic responses to sodium metabisulfite. It is used as a disinfectant, antioxidant, and preservative
  • The primary use of sodium metabisulfite is in the mining industry where it is used to control the depression of pyrites and sphalerite minerals.
  • As a strong reducing agent, sodium metabisulfite is used in the treatment of water, wastewater, and garbage. In the chemical industry, it is a frequent reducing agent. In the pulp and textile industries, sodium metabisulfite is also utilized as a bleaching agent.
  • Sodium Metabisulfite is a leather processing compound that helps to avoid the development of toxic hydrogen sulphide gas during the deliming process. It's utilized in the production of acrylic sheets, as well as in the photographic industry.
