The aim of this study is to examine the possible use of ion-exchange resin on Dowex AG 50x8 in separating Y-90 from Sr-90 which then could be applied in the basic of manufacture of producing Sr-90/Y-90 generator for the production of radiopharmaceutical cancer therapy. The findings showed that a distributive coefficient of Sr-90 and Y-90 with HCl 6 N solvent showed that distributive coefficient of Sr-90 in cation-exchange resin on Dowex 50x8 was greater than Y-90. Y-90 in HCl 6 N solvent was more easily eluted, while Sr-90 was bound to resin.. In conclusion, resin on Dowex AG 50x8 with HCl 6 N elution solvent might be able to separate Y-90 from Sr-90 as the basis for Sr-90/Y-90 generator.

Aim and Objective: The present study was performed with the aim to develop an efficient and environmentally benign protocol for the synthesis of biologically siginifcant 3, 4-dihydropyrano[c]chromenes using a new catalytic material. The protocol involves the use of a reusable, environment friendly materials and solvents with operational simplicity. Materials and Methods: Carbon microsphere supported copper nanoparticles (Cu-NP/C) prepared from loaded cation exchange resin were synthesized, characterized with well versed analytical techniques such as XRD, SEM and Raman spectroscopy and the synthesized material was used as a catalyst for the environmentally benign synthesis of 3,4-dihydropyrano[c]chromenes. Results: The formation of carbon microsphere supported copper nanoparticles (Cu-NP/C) prepared from loaded cation exchange resin was confirmed by XRD, SEM and Raman spectroscopy which was employed as a heterogeneous material for the synthesis of 3,4-dihydropyrano[c]chromenes. The products formed were characterized by the analysis of spectroscopic data - NMR, IR and mass. The safe catalytic system offers several advantages including operational simplicity, environmental friendliness, high yield, and reusability of catalyst and green chemical transformation. Conclusion: Herein we report an easy and efficient protocol for the one-pot synthesis of dihydropyrano[ c]chromenes using environmentally benign MCR approach in ethanol as the green solvent. The method developed herein constitutes a valuable addition to the existing methods for the synthesis of titled compounds.
