SEARCH FOR CHEMICAL-SEPARATION OF ELEMENT-106 HOMOLOGS IN HF AND HF-HCL MEDIA

In order to study the chemical properties of element 106 in aqueous me dia, fast, efficient and reproducible chromatographic separations were tested on its assumed homologues: Mo, W and U. Corroborative static a nd dynamic off-line experiments have shown that after fixation of thes e three elements on an anion-exchange resin in HF medium, selective el ution could be achieved by using suitable concentrations of HCl-HF and HCl solutions. Separations of short-lived W isotopes, produced throug h heavy ion irradiation were also performed on-line.
