A study of the extraction of polonium from aqueous solutions containing α-hydroxyisobutyric acid (α-HIBA) was performed with four different extractants, di-n-octyl sulphide (DOS), Cyanex 272, Cyanex 301 and Cyanex 302, dissolved in toluene. The extracted complex for DOS at low α-HIBA concentrations is most likely PoO(α-HIB)2·2DOS, while at higher α-HIBA concentrations there seems to be a solvating effect implicating an extracted complex of the type PoO(α-HIB)2(α-HIBA)2·2DOS. For the extraction… CONTINUE READING
