Description

Extraction of Zr(IV) by Aliquat 336 is achieved only above 6M HCl, whereas presence of thiocyanate ions results in the extraction of the same from low HCl concentrations (0.1-4.5M). Mixtures of Aliquat 336 with neutral donors like DOSO, TBP and TOPO result in synergism in the extraction process. By suitable regulation of extractant and acid concentrations, separation of 95Zr-95Nb and 95Zr-181Hf is possible. (author). 5 refs
