摘要：
The proton rich Ru-97, a potential candidate for nuclear medicine, was produced for the first time through the Nb-nat(Li-7, 3n)Ru-97 reaction. A natural Nb foil of 20 mg/cm(2) thickness was irradiated with 32 MeV Li-7 beams to attain the yield of similar to 1 MBq/mu A h for Ru-97. The no-carrier-added Ru-97 was separated from the bulk niobium by liquid liquid extraction (LLX) and solid liquid extraction (SLX) techniques. Liquid cation exchanger, di-(2-ethylhexyl)phosphoric acid (HDEHP) dissolved in cyclohexane was used in LLX and solid cation exchanger, DOWEX-50 was used for SLX in HCl. The LLX technique was found to be superior to the SLX technique with respect to radiochemical yield and purity of the radionuclide Ru-97.
