Combined Resins with Color Indicator


Merck’s mixed-bed ion exchangers are a combination of strongly acidic cation exchangers and strongly basic anion exchangers. They include a convenient color indicator, which is characteristic for strongly basic anion exchangers. When loaded, the color indicator of Amberlite MB-3 changes from blue to brown. Transfer into the Na+/Cl- form can be successfully achieved using 10% sodium chloride solution. However, regeneration of mixed-bed ion exchangers back to the H+/OH- form is not possible under laboratory scale conditions.

Features and Benefits

  • Combination of strongly acidic cation exchangers and strongly basic anion exchangers
  • Blue-to-brown color indicator
  • Easy transfer into Na+/Cl- form

Range of Applications

  • Water demineralization
