    Summary
    A chemical separation system was developed to separate group 4 and 5 elements using extraction from HCl/HF solution into methyl-isobutyl-ketone (MIBK). The system is proposed to be applied for a confident assignment of the spontaneous fissioning radionuclide produced as decay product of element 115 either as dubnium (Db, Z = 105) or rutherfordium (Rf, Z = 104). Moreover, extraction systems are proposed allowing the investigation of chemical properties of Db in comparison to the properties of its lighter homologs Nb and Ta.
