Separation of no-carrier-added 97Ru from 11B-induced Y target by encapsulation of 97Ru into calcium alginate hydrogel beads

97Ru radioisotope, a promising candidate for radiopharmaceutical applications was produced by natY(11B,3n) 97Ru reaction with 40 MeV projectile energy. Calcium alginate (CA) hydrogel beads, an environmentally benign matrix, were used for separation of no-carrier-added (NCA) 97Ru from the bulk yttrium target through adsorption–desorption experiments with a high separation factor (S Ru/Y = 2.6 × 104). It was also possible to encapsulate high purity 97Ru in CA hydrogel beads.
