Economical and Effective


Weakly basic anion exchangers have an effective pH range of 0 to 7. One of the advantages these resins offer is their excellent regeneration capability. Due to their weak basicity, they can be easily regenerated through treatment with NaOH, Na2CO3 or NH3, with only a slight loss of the theoretical amount. This flexibility makes weakly basic anion exchangers a highly economical resin to use and reuse.

Features and Benefits

  • Effective from pH 0 to 7
  • Good regeneration capabilities
  • Economical in use
