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 sol utions under on-line conditions using continuous chromatography with the mu lti-column technique, K-d values and the charge of the W species were deter mined. In order to achieve an effective separation of mother (W) and daught er (Ta), also the sorption of Ta from HNO3/HF solutions on various anion ex change resins with different functional groups was studied. This investigat ion serves the purpose to select a suitable anion exchange resin for planne d experiments with Sg.
