Mixed-bed Ion Exchangers
Combined Resins with Color Indicator |
MilliporeSigma’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
