A powerful ion exchange assist maintains its ability around a wide pH variety, whereas a weak one particular loses capability if the pH no more matches the acid dissociation regular (pKa) of its functional group.
The choice of the exchanger is dependent upon the demand of particle for being divided. To individual anions “Anionic exchanger is utilized, to different cations “Cationic exchanger is utilised.
