During dynamic column experiments, the following general criteria were studied: comparison of germanium sorption on the sorbent in protonated and free base forms, optimal pH-range for sorption and the effect of concentration of germanium and accompanying anions on breakthrough capacity. The optimal pH range for sorption of germanium oxoanions onto the studied resin is 6-9. For selective uptake of germanium oxoanions sorbent must be in the free base form. Effective desorption of germanium oxoanions was achieved with 7 BV of 1 mol.L-1 HCl. %K germanate %K methyl-amino-glucitol resin %K sorption %U http://iel.vscht.cz/articles/1803-4039-02-0046.pdf
