An example of the application of dynamic ion-exchange chromatography for the direct separation of rare earths is shown in Fig. 1.22. The sample was a sodium hydroxide leach solution from an aluminium processing operation and contained high concentrations of sodium, iron and aluminium. Due to matrix interference, these solutions could not be accurately analysed by inductively coupled plasma emission spectroscopy. Fig. 1.22 shows the chromatogram when the sample was separated by dynamic ion-exchange... 

As regards the layers, ready-to-use alkyl-bonded silica plates were found to have many advantages over the previously employed home-made plates. An appropriate term proposed for this chromatographic technique is surely dynamic ion-exchange chromatography. The method can be applied to separation of a wide variety of ionic compounds and classes of compounds (see Table 2).
