Basic Type Of Ion Exchange Resin
According to the "The Structure of Ion Exchange Resin " section, the functional group of the resin determines the properties and uses of the resin, so the classification of the resin and the functional groups are classified: 1、 Strong acid cation exchange resin SAC -sulfate group-SO3H SAC is capable of dissociating H+ and exhibit strong acidity, could be cation exchanged at any pH, and regenerated with acid. 2、 Weak acid cation exchange resin WAC - carboxyl -COOH WAC is capable of dissociating H+ and exhibit weak acidity. It can be cation exchanged in alkaline, neutral or slightly acid solutions，and generally regenerated with acid. 3、 Strong base anion exchange resin SBA - quaternary ammonium-NR3OH SBA is highly alkaline due to dissociation OH- in water. It can be anion exchanged at any pH, and are typically regenerated with NaOH. 4、 Weak base anion exchange resin WBA - primary amine-NH2，secondary amine-NHR,Tertiary amine-NR2 WBA can dissociate OH- in water and shows weak al...
