Databases on the coextraction of Th or Pu with Tc into 30% TBP in hydrocarbon diluent at 25°С are presented. The coextraction leads to mutual enhancement of the extraction of all the elements. The interactions in the system are described within the framework of a new approach to modeling, using the previously suggested and additional equations of concurrently occurring chemical reactions. The apparent equilibrium constants of these reactions are calculated.
