Abstract
Scandium was quantitatively extracted with 0.1 mol dm-3 Aliquat 336S in xylene at pH = 6.0 from 0.01 mol dm-3 ascorbic acid. It was stripped with 1 mol dm-3 hydrochloric acid and determined as its complex with Arsenazo III. It was separated from binary mixtures by exploiting the difference in the extraction behavior from ascorbic acid. Several separations were accomplished by process of selective stripping with concentrated hydrochloric acid. Many interesting separations of scandium from associated elements like yttrium, thorium, uranium, and molybdenum have been carried outKeywords
