Sodium Metabisulfite

Sodium metabisulfite is a white crystalline powder with a slight sulfur dioxide odor; it is non-volatile, decomposes before melting (typically above 150 °C), and is highly water-soluble. It is an inorganic sulfite salt, classified as a reducing agent and sulfur-containing compound. Industrially, it serves primarily as a preservative, antioxidant, and bleaching agent, and functions as a source of sulfur dioxide in chemical synthesis. Key application areas include food and beverage preservation, winemaking, water treatment, textile dyeing and printing, and as a reducing agent in photographic developers and polymerization processes.

Sodium metabisulfite (SMBS, Sodium disulfite) is a white, granular solid sodium salt. an inorganic compound made up of sodium, sulfur, and oxygen, and used in many industries:in the pulp and paper industry, in the photographic industry and in the various other industries as a bleach or dechlorinator.Food Grade sodium metabisulfite may be used as a food preservative. It is also commonly added to various food products and wines as a preservative.Sodium metabisulfite can also be used in the manufacture of other chemicals, Used in production of cleaning agents, detergents, and soaps.It also acts as a corrosion inhibitor in oil and gas industry, as a bleaching agent in the production of coconut cream, as the source of sulfur dioxide and in the destruction of cyanide in commercial gold cyanidation processes.Gold mining industry: It is utilized in the precipitation of gold from auric acid as well as in the waste water treatment to remove hexavaent chromium as trivalent chromium by precipitation after reduction.Preservative in photo developer solutions, it is used in photography.Oxygen scavenge:it plays as an oxygen scavenger to eliminate the dissolved oxygen in wastewater and in pipes.Sodium metabisulfite may be used as an initiator during the cross-linking polymerization of polybutadiene in the cores of the vesicle membranes.It may be added as an antioxidant during the preparation of stock solutions of 6-hydroxydopamine in various studies.Dechlorination in municipal wastewater, pulp & paper, power, and textile water treatment plants.
