SEPLITE ® Strong Base Anion Resin

The Strong Base Anion Exchange Resin( SBA 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 exchanger 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.
