| Popis: | Ion-exchange behaviours of Zr(IV), Nb(V), Ta(V) and Pa(V) on the anion exchanger Dowex 1-X8 are investigated first in a wide variety of aqueous mixed hydrochloric acid-hydrofluoric acid and secondly in the same aqueous system mixed with various organic solvents. Equilibrium adsorptions of these four elements as a function of hydrochloric acid concentration as well as hydrofluoric acid concentration, or both acid concentrations, were found to be strongly differentiated. This fact can be utilized for convenient separations of these elements from each other. Based on the equilibrium adsorption results, the possible complex formation of the metal ions and the separation possibilities for the elements are discussed. |
