Description

Barium Sulfite CAS NO 7787-39-5 is an inorganic chemical compound primarily used as a specialty reducing agent and precipitant in various industrial processes. Its commercial value lies in its ability to remove dissolved oxygen and act as a source of sulfite ions for controlled chemical reactions. This product is essential for manufacturers in sectors such as water treatment, specialty chemical synthesis, and paper production, where precise control over redox conditions is required.

Application

• Water Treatment: Acts as an oxygen scavenger and reducing agent in boiler feed water and industrial wastewater systems to prevent corrosion.
• Chemical Synthesis: Serves as a sulfonating or reducing agent in the production of specialty organic chemicals and dyes.
• Pulp & Paper Industry: Used in certain bleaching and chemical recovery processes within paper manufacturing.
• Analytical Chemistry: Employed as a reagent for gravimetric analysis and in laboratory procedures requiring sulfite ions.
• Precipitant: Utilized to precipitate specific metal ions from solution in metallurgical and purification applications.
• Photographic Industry: Functions in some photographic developing solutions as a preservative.
