Abstract

Ion exchange equilibria in batch systems have been examined to see how the distribution of ions between the ion exchanger and the solution depends on the dilution of the solution. The exchanger was Amberlite IR-120. The following exchanges were studied· K +-H+ Mg++-Ca ++ Ca++ -H+ Ba++ -H+ Ce3 +-H+ and La3 + H+. It has been found that dilution of the system causes the ion of higher affinity to pass into the resin phase. This effect is more pronounced for the exchange of ions of unequal charge than for those of the same charge.
