| Abstract: | The selectivity of glass type mixed Zr+Ti phosphates with various Ti contents has been investigated toward rare earth metal ions. The kd values were determined by radiotracer technique both in HCl and HNO3 solutions of various concentrations. At room temperature and at pH=4 the following selectivity orders were found: Yb>Tm Eu>Sm>La (HCl) and Eu>La>Sm>Yb>Tm (HNO3). |
