Purolite® A100, Weak Base Anion Resin, Free Base Form is a macroporous polystyrenic weak base anion resin having tertiary amine functionality. A100 is designed to exhibit high operating capacity in removing strong acids formed after decationizing water through a strong acid cation resin like C100H. Because of its special porosity characteristics A100 shows excellent properties for removal of naturally occurring organic species from waters along with superior elution efficiency of the organics during regeneration. A100 also shows excellent resistance to osmotic shock as well as being physically resistant to mechanical breakage. Regeneration with caustic soda requires only 125% of the stoichiometric equivalent when related to the ionic loading on the resin at the exhaustion point. The rinse characteristics are good and minimum volumes of decationized water are required to rinse down to a conductivity of 50 μS/cm.
