Product Description

Product Description

Sodium sulfite (Na₂SO₃) is an inorganic compound that appears as a white crystalline powder or particle, easily soluble in water, with an alkaline aqueous solution and slightly soluble in ethanol. It has reducibility and can be oxidized to sodium sulfate (Na₂SO₄), commonly used as an industrial deoxidizer, preservative, and bleach. Used as an antioxidant (E221) in food processing to prevent browning of fruits and vegetables; As a protective agent for developing solutions in the photography industry; Used in textile printing and dyeing to remove residues. In addition, it is also used for wastewater treatment, neutralizing acidic substances and precipitating heavy metals. Sodium sulfite needs to be sealed and stored to avoid contact with oxidants, as it is prone to oxidation in humid air and may release toxic during high-temperature decomposition

Application

1).Water treatment: used as a dechlorination agent to remove residual from tap water and wastewater; Used as an oxygen scavenger in boiler water treatment to prevent metal corrosion.

2).Chemical industry: used as a reducing agent in organic synthesis processes such as dyes, pesticides, and pharmaceuticals; Used for preparing chemicals such as sodium thiosulfate (baking soda).

3).Textile and papermaking: used as bleaching and dechlorination agents in the printing and dyeing industry; Used in the papermaking industry to bleach pulp and reduce the impact of lignin.

4).Photography industry: As a protective agent for developing solutions, it prevents premature oxidation and failure of the developer.

5).Environmental applications: used for exhaust gas treatment, absorbing SO₂, reducing air pollution; In the treatment of electroplating wastewater, hexavalent chromium is reduced to low toxicity trivalent chromium.

6).Other uses: as anti-aging agent in rubber industry; Used as a reducing agent for laboratory analysis, such as iodometric method.
