摘要

Irradiation of natZr target by 10 MeV proton beam produced 90Nb via 90Zr(p, n)90Nb nuclear reaction. This study reports the potential of a nature resourced chemical, curcumin, as a solid extractant towards the separation of no-carrier added (NCA) 90Nb from bulk Zr. Radiochemical separation was carried out by solid–liquid extraction (SLX) technique using curcumin as solid phase and varying concentration of HCl as liquid phase. About 53% of NCA 90Nb was extracted by 100 mg curcumin at 6 M HCl along with minuscule contamination from bulk Zr. High separation factor, ~ 1.8 × 103 was achieved in this condition.
