Zur Untersuchung von Gleichgewichten instabiler Komplexe und die Bestimmung der Beweglichkeiten der einzelnen Spezies mittels Gegenstrom-Ionenwanderung / Investigation of the Equilibrium of Unstable Complexes and the Determination of their Mobility by Means of Countercurrent Ion Migration

Abstract

In a countercurrent ion migration process the ion of an element (e. g. a metal cation) can form various unstable complexes with the anion of the countercurrent electrolyte. The total concentration of such an element in its stationary and locally constant distribution in a countercurrent ion migration column is then determined by the average mobility of all equilibrated species containing this element. From stationary distributions in their dependence on concentration the mobilities of the various species can be determined if the constants of the different equilibrium stages are known and vice versa.
