Abstract

In order to reduce the time requirement for ion exchange separations the kinetics of the elution of different ions was studied in the function of the grain size of the ion exchange resins. Using a counter current apparatus seven differents fractions could be separated in the case of commercial resin Dowex 1×10 and 50 W×12. Grain size was found to have a great influence on the shape of the elution curves. The finer and more homogenous the resins are the sharper are the peaks on the elution curves. These consderations were utilized for the separation of rare earth, alkaline and alkaline earth metals, respectively.
