Abstract: PURPOSE:To efficiently separate and capture Sc by treating an aq. soln. contg. Sc (III) ions with a porous resin impregnated with alkylphosphonic ester represented by a specified formula to adsorb Sc and by eluting the adsorbed Sc with an org. solvent. CONSTITUTION:An aq. soln. contg. Sc (III) ions is treated with a porous resin impregnated with alkylphosphonic ester or alkylphosphoric ester represented by the formula (where each of R<1> and R<2> is >=6C alkyl and R<1> and R<2> may be different from each other) to adsorb Sc on the resin. The aq. soln. contg. Sc (III) ions is treated as an aq. soln. acidified with an acid such as hydrochloric acid and the concn. of the acid is controlled to >=1N. Cross-linked polyacrylic ester may be used as the porous resin. The porous resin is then treated with an org. solvent to elute the adsorbed Sc.
