DESCRIPTION

NEOVERSENE chelating agent is an aqueous solution. NEOVERSENE is strongest, most versatile, and widely used chelant for controlling metal ions over a broad pH range in aqueous system. It will not chelate monovalent metal ions such as sodium or potassium, but will chelate most multivalent metal ions (e.g., Fe, Cu, Mn, Ca, and Zn) in a 1.1 molar ratio. The chelation reaction is virtually instantaneous in most cases. Calcium and other alkaline earth metals are most effectively chelated above pH 4. NEOVERSENE chelates most transition metals below pH 12. NEOVERSENE is completely miscible with water, but is not soluble in organic systems.

NEOVERSENE is attacked, however, by strong oxidizing agents such as hypochlorite bleach.

ADVANTAGES

  • NEOVERSENE is stable under widely varying conditions of temperature, acidity, alkalinity, and the presence of other chemicals.
  • NEOVERSENE is effective by an ample rank of Ph
