Anion Exchange Resin
HUAYUE® Strong Base Anion Exchange Resins (SBA）
The Strong Base Anion Exchange Resin is the type of ion exchange resin with functional group of quaternary ammonium, which is strongly alkaline and dissociates just like NaOH and KOH.
In chemical structure, there are two types of strong base anion exchange resin with different alkalinity strengths, Type Ⅰ with a trimethyl ammonium group, Type Ⅱ with a dimethylethanol ammonium group. Type Ⅰ shows a higher alkaline than Type Ⅱ. Compared with type 1 strong base anion, this resin is more suitable for applications needing good rinsing performance and excellent regeneration efficiency.
The Strong Base Anion Exchange Resin shows an excellent physical and chemical stability, which is capable of exchanging the different anion under a wide range of pH.
The Strong Base Anion Exchange Resin is mainly used in water treatment, to produce high purity demineralized water, making use of the ability to adsorb anions strongly.
HUAYUE® Weak Base Anion Exchange Resins (WBA)
The Weak Base Anion Exchange Resin with primary, secondary, tertiary amine or mixed amine group as active functional groups show different strengths of alkalinity. Most weak Base Anion 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 weak base anion 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 strong base anions.
The weak base anion exchange resin is easier to regenerate than the strong base resin, and can be efficiently regenerated with a small amount of sodium hydroxide.
Weak base anion 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.
