| Abstract: | The sorption behavior of microamounts of Hf and Ta on DOWEX 50×8 and DOWEX 1×8 from aqueous HCl/HF solutions has been investigated. Suitable separation conditions for these two elements on cation exchange resins were found in solutions containing 1.5M HCl/10–4M HF and 0.05M HCl/10–3M HF. Kinetic experiments showed that the system can be applied in high speed on-line separations.This work was supported by Bundesministerium für Forschung und Technologie. |
