Extraction of Scandium Halides with Mixtures of Tributylphosphate and Molecular Iodine

Abstract

The extraction of scandium chlorides, bromides and iodides from aqueous solutions with mixtures of tributyl phosphate (TBP) and molecular iodine was studied. Extraction of scandium halides using TBP with the addition of iodine increases by more than 100 times. Salt distribution coefficients increase in the series ScCl3
