Description

The efficiency of the separation of Zr(4) and Hf(4) by ionic exchange had been compared as function of the variable molar ratio SO42- : Zr(4) + Hf(4), from which the last both being in complex forms. The cation exchanger Wofatit KPS and the solutions containing sulphate complexes of zirconium and hafnium with addition of 0,5 - 1 M nitric acid have been used. The most advantageous results have been obtained for the solutions having the molar ratio SO42- : Zr(4) + Hf(4) = 9.1. (author)
