活性炭吸着と陰イオン交換を用いるウランからの²³⁴Thのミルキング

抄録

A rapid and simple procedure for the preparation of carrier-free ²³⁴Th for use as a tracer has been devised. A 0.01 mol·dm^-3 HC1 solution (120 cm³) of uranium (1.6 mol·dm^-3) is kept contact with active charcoal. After the bulk uranium solution is removed, ²³⁴Th adsorbed on the charcoal is eluted with a 6 mol·dm^-3 HC1 solution (120 cm³) . A small amount of uranium remaining in the solution of ²³⁴Th is completely removed by passing the solution through anion-exchange column.
