Application

Dowex MAC-3 was used in the separation and pre-concentration of metal ions in alcohol. It was also used as packaging material in chromatographic columns for purification.

Weakly acidic cation exchanger for water treatment, dealkalization, purification of antibiotics, pharmaceuticals and amino acids, etc. The macroporous matrix gives the resin good resistance to osmotic shock, while maintaining a high regeneration efficiency.
