在pH为2.5 ~ 4.5的条件下，用4 × 10(-2) mol dm-3 - 18-crown-6从4 × 10(-2) mol dm-3苦味酸溶液中定量提取钪。用0.1 mol dm-3硝酸剥离，在650 nm处测定其与偶氮胂的配合物。它在多组分混合物中从钇、镧系元素、锆、铪、钒、铌和铀中分离出来。对岩石样品中的钪进行了分析。
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.
