Barium sulfite

Barium sulfite (CAS 7787-39-5), also referenced as barium sulphite, is an inorganic barium salt used industrially as a reducing and preservative agent.

Where is Barium sulfite used?

• Water treatment: oxygen scavenger and pH buffer that protects process equipment from corrosive degradation
• Textile and leather processing: dyebath preparation and tanning liquors
• Pulp and paper: bleaching and pulping stages to moderate oxidative conditions
• Industrial formulations: preservation where sulfite-based biocidal activity is required
• It controls oxidative degradation and microbial activity in process streams and treatment baths.

Good to know: Buyers should confirm purity specifications and barium content with suppliers before finalizing procurement orders, as these vary by production source and intended end use.
