Sr was produced via Y(n, p) Sr using yttria as target in Fast Breeder Test Reactor (FBTR), Kalpakkam, India. A radiochemical procedure has been developed for the separation of bulk yttrium using TBP by solvent extraction followed by purification of Sr source by ion exchange chromatography using the cation exchange resin Dowex 50WX8 (100-200 mesh) and nitric acid of variable molarity as eluant. The present study establishes the purification of Sr source from the other radionuclidic impurities like Y, Zn, Mn, Co, Rb, Ir, Ru, Sn, Ce, Tb, Eu etc. produced during the irradiation of yttria by using the complexing agent tri-sodium tri-meta phosphate (SMP) in nitric acid medium instead of nitric acid alone as an eluant. The purification was achieved by using 0.1 M SMP as complexing agent which was optimized based on the distribution ratio data and final elution of Sr fraction was obtained in nitric acid medium. This resulted into a faster purification of Sr source in a smaller volume of eluant. Purity of Sr source from the cross contamination of the complexing agent SMP was also ensured.
