Development of a method for calculating the equilibrium and kinetics of ion exchange on a weak acid resin in a ternary system H+-Ca2+-Mg2+

Description

In technical applications ion exchange resins are applied in filters. The breakthrough behaviour of such filters can be calculated using mathematical relationships for equilibrium and kinetics. An according method has been developed for a ternary ion exchage problem on a weak acid resin. Theoretical results are verified by means of experimental data. (orig.)

Abstract (German)

Ionenaustauscher werden in technischen Anwendungen in Filtern eingesetzt. Das Durchbruchsverhalten solcher Filter kann berechnet werden, wenn die mathematischen Beziehungen zur Gleichgewichtslage und zur Austauschkinetik bekannt sind. Am Beispiel eines ternaeren Systems werden die Modellansaetze zur Berechnung der Gleichgewichtslage und der Austauschkinetik an einem schwach sauren Harz entwickelt. Zur Ueberpruefung des Ansatzes werden die theoretisch und experimentell ermittelten Daten verglichen. (orig.)
