Section: claims

1. A method for generating 43Sc, which comprises:performing a nuclear reaction of 42Ca(d,n)43Sc using enriched 42Ca and deuteron beam energies of 3 to 12 Mev. 2. The method according to claim 1, which further comprises:irradiating the enriched 42Ca target in form of CaCo3, Ca(NO3)2, CaF2, or CaO powders or Ca metal having a 42Ca content of 50% or higher with \hte deuteron beam thereby turning 42Ca content into the 43Sc;dissolving irradiated enriched 42Ca target in acidic solution and passing a resulting solution through a first column loaded with DGA resin in order to absorb 43Sc ions;eluting absorbed 43Sc ions by rinsing the first column with HCl into a second column loaded with a cation exchange resin in order to sorb 43Sc in the second column; andperforming an elution of the 43Sc from the second column using NH4-acetate/HCl or NaCl/HCl. 3. The method according to claim 1, which further comprises:evaporating an effluent from the first column containing an enriched Ca isotope to dryness in order to form a resultant white residue;dissolving the resultant white residue in deionized water and adjusted to a pH of 4.5-5 with ammonia solution and HCl, respectively, in order to form a solution containing solved Ca(II) ions;precipitating a solved content of Ca(II) as Ca-oxalate by adding ammonium oxalate solution; andfiltering precipitated Ca-oxalate and transferring an oxalate to a carbonate by slowly heating filtered Ca-oxalate.
