摘要：

Technetium(99) poses a difficult problem at many nuclear waste disposal sites, as there have been multiple incidents of its release to the environment due to large quantities of fission products disposed in storage tanks. Tc is mostly present under two oxidation states, Tc(VII) and Tc(IV) and the separation of Tc(IV) from Tc(VII) is often crucial for laboratory-scale work performed for the study of Tc. This work offers a method for the rapid separation of Tc(IV) from Tc(VII), using a solvent extraction system containing iodonitrotetrazolium chloride and chloroform.
