SODIUM CHLORITE

Sodium Chlorite (NaClO₂) is a white crystalline powder widely used as a strong oxidizing agent. It is a vital compound in water treatment, disinfection, bleaching, and chemical synthesis. Known for its stability in storage and ability to release chlorine dioxide upon acidification, Sodium Chlorite is highly valued in industrial and environmental applications.

Applications

1. Water Treatment

• Disinfection: Generates chlorine dioxide to eliminate bacteria, viruses, and biofilms in drinking water systems.
• Odor and Taste Control: Used to improve the sensory qualities of water.
• Industrial Wastewater: Treats wastewater in industrial processes, preventing contamination.

2. Pulp and Paper Industry

• Bleaching Agent: Used for bleaching wood pulp in environmentally safer processes.
• Delignification: Removes lignin while preserving the cellulose structure.

3. Textile Industry

• Bleaching Textiles: Efficiently brightens and whitens fabrics without damaging fibers.
• Dye Preparation: Acts as a pre-treatment agent for dye processes.

4. Medical and Pharmaceutical Uses

• Antimicrobial Agent: Included in formulations for sanitizing surfaces and equipment.
• Oral Care Products: An ingredient in mouth rinses and tooth whiteners for its oxidizing properties.

5. Food Processing

• Preservation: Sanitizes and extends the shelf life of fruits, vegetables, and poultry.
• Surface Disinfection: Sterilizes food contact surfaces in manufacturing plants.

6. Other Industrial Uses

• Oil and Gas: Enhances oil recovery by controlling bacteria in injection water.
• Electronics Manufacturing: Used in circuit board cleaning and etching.

Safety and Handling

Hazards:

• Sodium Chlorite is an oxidizing agent and poses a fire hazard when in contact with organic materials.
• Inhalation of dust or fumes can irritate the respiratory system.
• May cause severe skin and eye irritation upon direct contact.

Precautions:

• Personal Protective Equipment (PPE):
  • Use gloves, goggles, and protective clothing when handling.
  • Employ a respirator if dust or fumes are present.
• Handling Guidelines:
  • Avoid creating dust and minimize exposure to skin and eyes.
  • Do not mix with acids unless under controlled conditions.
• Storage:
  • Store in a cool, dry, and well-ventilated area away from organic materials and acids.
  • Keep the container tightly closed to prevent moisture absorption.

First Aid Measures:

• Inhalation: Move to fresh air immediately. Seek medical attention if symptoms persist.
• Skin Contact: Wash thoroughly with soap and water. Remove contaminated clothing.
• Eye Contact: Flush with water for at least 15 minutes and consult a physician.
• Ingestion: Do not induce vomiting. Seek immediate medical advice.

Disposal:

Dispose of Sodium Chlorite in accordance with local and national environmental regulations. Avoid releasing it into natural water bodies.
