Properties:
Clear, colorless to slightly yellow aqueous solution with excellent chelating properties. Highly stable and effective across a wide pH range.
Application:
Scale & Corrosion Inhibitor: Pentasodium DTPA effectively binds metal ions (Ca²⁺, Mg²⁺, Fe³⁺) in water systems, preventing scale formation and corrosion in boilers, cooling towers, and pipelines.
Stabilizer & Builder: Enhances the performance of detergents and cleaners by sequestering hardness ions, improving surfactant efficiency, and preventing redeposition of dirt.
Pulp & Paper Industry: Protects cellulose fibers during hydrogen peroxide bleaching by chelating transition metals (Mn, Fe, Cu) that catalyze degradation.
Agriculture & Textiles: Improves nutrient availability in fertilizers by preventing precipitation of metal ions.
Analytical Chemistry: Used in titrations and spectrophotometry for metal ion quantification.
Package and Storage:
- Packaging: 25 kg, 200 kg plastic drums, or IBC tanks.
- Storage: Sealed in a cool, dry place at room temperature. Avoid prolonged exposure to sunlight.
