Purolite® A847, Weak Base Acrylic Anion Resin, Free Base Form is a unique weak base resin, with a gel acrylic divinylbenzene matrix and tertiary amine functionality. The special properties are associated with the extremely low rinse requirement after regeneration with caustic soda together with an increase in useful operating capacity of up to 10% over similar resins A847 shows excellent resistance to organic fouling and because of its ability to adsorb and desorb organics efficiently, can act as a guard column for strong base polystyrene resin that may be placed downstream in a demineralisation system. A847 shows unique resistance against osmotic shock attrition as well as being physically resistant to mechanical breakage. Efficiency of regeneration is good and only 125% to 135% of stoichiometric caustic soda is required to regenerate the exhausted resin.

  • Application - Water Treatment - Low Rinse Volumes and High Purity
