Abstract: In the batch experiment with W, Ta, Hf, Lu and Mo as radiotracers, a new rapid radiochemical isolation procedure for clement tungsten has been developed by using radiochemical separation methed and y spectrum measurement technique. With Voltalef powder carried 2% (W/V) BPHA(Benzoylphenylhydroxylamine)C5H11OH (iso-amylalcohol) organic solution, radioactive W was adsorbed on the Voltalef column in the 4mol/L hydrochloric acid system. Hf, Lu and Mo fractions passed through the Voltalef column rapidly and partial Ta activities retained on the Voltalef column, respectively. Following this, W fraction was eluted completely with 1%Na3C6H5O7 (sodium citrate)-5%(W/V) NH,OH solution and no Hf, Lu, Ta and Mo activities passed through the Voltalef extraction chromatographic column. The procedure was simultaneously used to isolate W from Er target bombarded with a low energy 12C beams. By means of this separation eystem, it is one of the possible way to develop an isolation procedure of Sg, supposing the chemical property of Sg is similar to that of tungsten.
