Weak Base Anion Resins with Acrylic or Styrenic Backbones

Yellowish styrene series macroporous weak base anion resins

Weak base anion resins are the only type of ion exchange resins that do not have exchangeable ions. These resins absorb free inorganic acids(Cl-and SO42-). Characterized by high regeneration efficiency and exchange capacity, weak base anion resins generally work with strong base anion resins and are widely used in pharmaceutical, food and chemical industries to remove organic, inorganic acids and organic matters from water.
