    The possibility of use of trifluoronitrotoluene an trifluoromethylphenylsulphone as a diluents in extraction separation of high radiotoxic strontium 90

  • Original language description

    The extraction of radioactive Sr by the solutions of heptachlorodicarbollylcobaltate in trifluoronitrotoluene (FS-3) and trifluoromethylphenylsulfone (FS-13) in the presence of linear (PEG-400) and cyclic (15-crown-5, benzo-15-crown-5 and 18-crown-6) polyoxyethylene compounds has been tested. It was found that both diluents are better extraction solvents than the nitrobenzene. The synergistic factor S for the extraction of strontium in the presence of PEG-400 increase in the order nitrobenzene < FS-3 <FS-13, in the presence of 15 crown-5 the order nitrobenzene < FS-3 " FS-13 has been found.

    Možnosti využití trifluoronitrotoluenu a trifluoromethylfenylsulfonu jako rozpouštědel při extrakční separaci vysoce radiotoxického stroncia 90

  • Czech description

    Byla sledována extrakce Sr roztokem dikarbollylkobaltitanu v trifluornitrotoluenu (F-3) a trifluoromethylfenylsulfonu (FS-13) za přítomnosti 15-crown-5, benzo-15-crown-5, 18 crown-6 a PEG-400. Bylo zjištěno, že hodnoty rozdělovacích poměrů Sr jsou ve všech sledovaných systémech o 0,5 až 1,5 řádu vyšší, než v analogických systémech. Synergistický faktor S pro extrakci stroncia za přítomnosti PEG-400 roste v pořadí nitrobenzen < FS-3 < FS-13, za přítomnosti 15 crown-5 bylo nalezeno pořadí nitrobenzen < FS-3 " FS-13.
