Product Description of Sodium dithionite CAS#7775-14-6
Sodium dithionite, also known as sodium hydrosulfite, sodium hydrosulphite, sodium sulfoxylate, or sulfoxylate, is a strong reducing agent. It is unstable under physiological conditions, with decomposition accelerating in acidic environments. When exposed to moisture, it is oxidized to hydrogen sulfite, sulfite, and hydrogen sulfate, and under strongly acidic conditions may release sulfur dioxide. In anaerobic environments, hydrogen sulfite and thiosulfate can form. After ingestion, hydrogen sulfite may be absorbed, rapidly metabolized, and mainly excreted as sulfate in urine.
Owing to its strong reducing ability and high reactivity with oxygen, sodium dithionite is widely used across various industries. Its applications include textile dyeing, pulp and paper bleaching to remove yellowing from cellulose-based materials, oxygen scavenging in boilers, conservation for removing iron stains from cultural artifacts, and water treatment to control iron-related discoloration during bleaching. It is also used in photographic processing, clay and ceramic production, wine making, leather processing, food and beverage industries, polymer manufacturing, cleaning formulations, gas purification, environmental remediation, metal recovery, and chemical processing.
Product Application of Sodium dithionite CAS#7775-14-6
Sodium dithionite (sodium hydrosulfite) functions as a reducing agent, sulfonating agent, chelating agent and decolorizing agent in aqueous systems and organic reactions. It is widely utilized in water treatment, gas purification, cleaning formulations, leather processing, polymer manufacturing and photography. In chemical enhanced oil recovery, it stabilizes polyacrylamide polymers to prevent radical degradation induced by iron ions. It also serves a key role in soil chemistry for iron content determination.
