    Re(VII) extraction by primary amine from aquous sulphuric acid solutions

  • Original language description

    In our work the experimental results on extraction of Re(VII) by primary amine PRIMENE JM-T are presented. The experiments were carried out with solutions of Primene JMT in non-aromatic solvents Spirdane 40 with respect of initial concentration of metalsand sulphuric acid. The results almost unambiguously confirm the anion exchange mechanism of extraction. Results for Re(VII) are compared with the analogical results for Mo(VI) measured before. The conditions for the preferable extraction of Re or the conditions for the preferable extraction of Mo were found.

    Extrakce Re(VII) primárním aminem z roztoků kyseliny sírové

  • Czech description

    V práci jsou prezentovány experimentální výsledky pro extrakci Re(VII) primárním aminem PRIMENE JMT, který byl rozpuštěn v nearomatickém ředidle Spirdane 40. Sledovala se závislost extrakce na koncentraci kovu a kyseliny sírové. Výsledky potvrdily mechanizmus výměny aniontů při extrakci. Dosažené výsledky byly porovnány s chováním solí Mo(VI). Byly nalezeny podmínky pro separaci solí Re(VII) a Mo(VI).
