The concentration analysis of Tc is the basis of the research of behavior of Tc. Tc is a P radiation nuclide. It’s half-life is 2.13 × 105 a. The concentration of Tc can be determined by its activity or by spectroscopic method using its complex with other substance. Tc samples in Purex may contain a large amount of U, Np and Pu. The disturbance of them should be eliminated when the concentration of Tc is analyzed. As collidine can extract heptavalent, Tc nearly quantitatively and the extraction ability for other elements is very low, it is possible to separate Tc from U, Np,
