Adsorptions of strontium and cesium ions on hydrothermally altered minerals of feldspar, lithia-mica and bauxite.
Year: 1984
Type: article
Abstract: The minerals, from which Li+ and K+ had been extracted in high extraction ratios, had high adsorbability of Sr2+ and Cs+ ions. Hydrothermal extraction residues of lithia-mica and, feldspar had high distribution coefficients (103∼404) towards Sr2+ and Cs+ ions in the aqueous solution. Although the red mud prepared from bauxite had high distribution coefficient of Sr2+ ion, it had low distribution coefficient of Cs+ ion.These iesidues' obtained by the hydrothermal treatment of aluminosilicate ores are expected as the promising immobilization matrix of 90Sr and 137Cs found in the nuclear fission wastes.
