Chelating Agent
- Chelating agents coordinating metal ions make complexes through erupting safe ring-shaped ions
● EDTA-4Na (carboxylic acid-based chelating agent)
- Tetrasodium Ethylene Diamine, Tetra Acetate
● DPTMPA (phosphoric acid-based chelating agent)
- Diethylene Triamine Pentamethylene Phosphonic Acid
● HEDP (phosphoric acid-based chelating agent)
- 1-Hydroxy Ethylidene-1, 1-Diphosphonic Acid
● Sodium Gluconare
- Sodium gluconate forms safe chelating compounds with Ca, Fe, Cu, Al and heavy metals.
