Industrial Applications & Functional Mechanisms

Core Function: High-efficiency chelating agent with superior metal ion sequestration capacity (Stability constant log K ~22.4 for Fe³⁺)

Primary Sectors:

  • Water Treatment: Scale inhibition in cooling towers (Effective up to 80°C)
  • Textile Processing: Peroxide stabilizer in bleaching operations
  • Agriculture: Micronutrient carrier in fertilizer formulations
  • Pulp & Paper: H₂O₂ stabilization in delignification

Operational Guidelines & Best Practices

Dosage Recommendations:

  • Cooling Water Systems: 5-15 ppm continuous feed
  • Textile Bleaching: 0.1-0.3% on fabric weight
  • Fertilizer Additive: 0.5-1.5 kg/ton compound

Compatibility Notes: Maintain pH >10 for optimal performance. Avoid strong oxidizers in closed systems.
