Product Details

The Weak Base Anion (WBA) Exchange Resin with primary, secondary, tertiary amine or mixed amine group as active functional groups show different strengths of alkalinity. Most WBA Exchange Resins with mixed amine group equiped a extremely high operating capacity with the ability to remove both strong and weak acids from solution.

There are two kinds of WBA exchange resins, Gel type and Macroporous type, which have acrylic backbone, styrene backbone or mixed backbone. Weak base anion exchange resins are more chemically stable and higher resistant to organic fouling than SBA.

The WBA exchange resin is easier to regenerate than the SBA resin, and can be efficiently regenerated with a small amount of sodium hydroxide.

WBA exchange resins are commonly used in pharmaceutical, food engineering, and chemical engineering, such as the removal of mineral acid, organic acids and other organic materials, especially for removal of high molecular weight organic matters from aqueous solutions under low pH condition.
