THE MECHANISM OF ELECTROLYTE ABSORPTION ONTO STRONG BASE-WEAK ACID AMPHOTERIC RESINS

Xu Hede(Dept. of chemistry, South China Normal University, Guangzhou 510631,China)  
Absorption of electrolytes is dependent on solution pH. At pH ≤2, amphoteric resins play a role as strong base resins; the absorption of electrolytes takes place according to the anion exchange mechanism, At pH2~7, the molecular sorption by breaking of innersalt bonds increases gradually. At pH≥7,the principal absorption is the molecular sorption by breaking innersalt bonds as well as ion exchange.At the same time, the ion selectivity obviously increases, which may be useful in the softening of concentrated NaCl solution.
