Abstract: Scandium was quantitatively extracted at pH 2.5-4.5 with 4.0x10(-2) mol dm-3 18-crown-6 in dichloromethane from 4.0x10(-2) mol dm-3 solution of picric acid. It was stripped with 0.1 mol dm-3 nitric acid and determined spectrophotometrically at 650 nm as its complex with Arsenazo-III. It was separated from yttrium, lanthanides, zirconium, hafnium, vanadium, niobium, and uranium in multicomponent mixtures. Scandium from rock sample was also analysed.
