Summary

Product identification

DIAION UBK Series Cation Exchange Resins

General Description

Resins with sulfonic acid (-SO₃H) as the functional group exhibit strong acidity and can exchange positive ions such as Na⁺ and Ca²⁺.

Strong Acid Cation Exchange Resins (SACERs)

• Can exchange cations in all pH ranges.
• Relatively stable at high temperatures (100-120°C).
• Applications include water treatment, purification of food and pharmaceuticals, and as reaction catalysts.
• The sulfonic acid group (-SO₃H) is strongly acidic and dissociates to -SO₃⁻ and H⁺.
• Ion exchange reactions involve the exchange of counter ions (H⁺ in this case).
• Can exchange counter ions with neutral salts as well as bases.

Regeneration

Regeneration is required to restore the resins to their original R-SO₃H form after use. This is typically performed using hydrochloric acid or sulfuric acid aqueous solutions.

Example Regeneration (Counter cation Na⁺):
