| Popis: | We have studied extraction behavior of group-6 elements Mo and W to search for suitable conditions for an on-line extraction experiment of their heavier homolog, seaborgium (Sg). Batch-wise extraction of carrier-free radiotracers 93mMo and 177,179,181W were carried out from 0.10 – 8.6 M H2SO4 and 1.0 × 10−4 − 5.0 M HF/1.0 M HCl into toluene with a quaternary ammonium compound, Aliquat336. Anionic sulfate complexes of Mo and W with charge − 2 were extracted with Aliquat336 from H2SO4 solutions with concentrations of [H2SO4] > 2 M. In HF/1.0 M HCl, oxyfluoro complexes of Mo and W with charge − 1 were interpreted to be formed and extracted with Aliquat336. From these results, favorable conditions for the extraction of Sg are discussed. |
