    LIQUID-SOLID EXTRACTION OF URANIUM (Ⅵ) IN PHOSPHORIC ACID WITH TAPO-WAX AND ITS SPECTROPHOTOMETRIC DETERMINATION

      Graphical Abstract
      • Abstract
    • Here is reported the separation of uranium (Ⅵ) in phosphoric acid by liquid-solid extraction with TAPO(Tri-Alkyl-Phosphine Oxide) and wax. The organic phase is stripped with 0.12 mol/1 NaF solution. The uranium is determined spectrophotometrically with Arsenazo Ⅲ and the fluoride ion is masked with 4% boric acid. Results of analyses of phosphoric acid samples by this method are given.
