title: Separation of no-carrier-added (93,94,94m,95,96)Tc from (7)Li induced natural Zr target by liquid-liquid extraction.
abstract: Charged particle activation was carried out on (nat)Zr foil by 42.5MeV (7)Li beam to produce (93,94,94m,95,96)Tc radionuclides. No-carrier-added (nca) technetium radionuclides were separated from co-produced (90,96)Nb and bulk Zr employing liquid-liquid extraction with the help of anion exchanger trioctylamine (TOA) diluted in cyclohexane and HCl. Bulk Zr was monitored by spiking (88,89)Zr produced by 20MeV proton induced reaction on (nat)Y target. The optimum separation was achieved at 0.1M TOA and 0.01M HCl. Technetium radionuclides were recovered from the TOA phase by stripping with 0.1M DTPA (diethylene triamine pentaacetic acid) dissolved in NaOH.
