Continuous on-line chromatography of short lived isotopes of tungsten as homolog of seaborgium (element 106)

We have studied the sorption of W on anion-exchange resins from HNO₃/HF solutions under on-line conditions using continuous chromatography with the multi-column technique. Kd values and the charge of the W species were determined. In order to achieve an effective separation of mother (W) and daughter (Ta), also the sorption of Ta from HNO₃/HF solutions on various anion exchange resins with different functional groups was studied. This investigation serves the purpose to select a suitable anion exchange resin for planned experiments with Sg.
