Product details
Product Overview
Sodium Sulphite (Na2SO3) is a versatile chemical compound used across various industries including food processing, water treatment, photography, and chemical manufacturing. With a minimum assay of 97%, this compound offers compositional accuracy and purity for specialized industrial uses.

Applications
Commonly used in the pulp and paper industry as a reducing agent and bleaching aid, Sodium Sulphite also serves as an antichlor in water treatment systems. In photography, it acts as a preservative and antioxidant. It is used as an enzyme inhibitor in food and drug processing, and as an oxygen scavenger in oil well floatation and boiler water systems.

Performance & Benefits
This food/photo-grade powder features a low impurity profile, with sulphate content ≤ 2.5%, iron ≤ 10 ppm, and heavy metals ≤ 20 ppm. It is free from contamination, has minimal moisture content (≤ 0.1%), and remains stable during storage and transportation.

Specifications
- Assay: ≥ 97% - Sulphate: ≤ 2.5% - Insolubles: ≤ 0.1% - Moisture: ≤ 0.1% - Iron (Fe): ≤ 10 ppm - Heavy Metals (Pb): ≤ 20 ppm - Form: Powder - CAS No.: 7757-83-7

Supply & Export Readiness
Distributed by Prinita Chem and packed in durable 25kg bags, this product meets global quality standards and is suitable for export. It supports high-volume industrial procurement for chemical manufacturers, water treatment facilities, food processors, and laboratories worldwide.

Frequently asked by buyers
What makes this Sodium Sulphite suitable for food and photographic applications?

This Sodium Sulphite meets strict purity criteria with a minimum assay of 97%, low iron (≤10 ppm), low sulphate (≤2.5%), and very low heavy metals (≤20 ppm), ensuring it is free from contaminants that could affect food safety or photographic material integrity.

How does the low moisture content benefit industrial usage?

With moisture content ≤0.1%, the powder remains free-flowing, reduces clumping during storage and transportation, and maintains stable performance, critical for processes requiring precise dosing and chemical reactivity.

Is this Sodium Sulphite compatible with water treatment systems?

Yes, it acts as an effective antichlor and oxygen scavenger in water treatment applications, helping to neutralize chlorine and protect equipment from corrosion.

Can this product be used in high-volume industrial procurement?

Absolutely, the product is supplied in 25kg durable bags designed for large-scale procurement and export, making it ideal for chemical manufacturers, water treatment plants, and food processing units.

What quality standards does this product comply with for export?

It meets global quality standards including precise assay levels, low impurity thresholds, and packaging norms ensuring it’s suitable for international shipping and industrial use.

How stable is the Sodium Sulphite during storage?

The product's minimal moisture and impurity levels ensure it remains chemically stable and maintains its performance characteristics during extended storage and transit periods.
