Abstract
Terbium and dysprosium are rare earth elements which are employed in the manufacture of advanced materials. Separating Tb(III) and Dy(III) is very complicated because their chemical properties are similar. In order to develop a separation process based on solvent extraction, extraction and scrubbing experiments were conducted using weak hydrochloric solutions..... More

Abstract
Cyanex 272 shows the highest separation factor for the rare earth elements from hydrochloric acid solution among the organophosporus acidic extractants, D2EHPA and PC 88A. Solvent extraction of Tb(III) from weak hydrochloric acid solution with an initial pH 3 to 6 was compared with Cyanex 272, its mixture with Alamine..... More
