Abstract

The chromatographic adsorption on γ-alumina and synthetic inorganic ion exchange materials of various metal cations dissolved in a fused lithium nitrate—potassium nitrate eutectic was studied. The results obtained seem to confirm that metal ions are adsorbed by ion exchange, although other mechanisms, e.g. oxide precipitation, or formation of insoluble phosphates, are possible. A relationship between the adsorption of the metal ions tested, the solubility of their oxides and the ionic potentials was found. Some conflicting results of other authors are discussed.
