摘要
Charged particle activation was carried out on Zr-nat foil by 42.5 MeV Li-7 beam to produce Tc-93,Tc-94,Tc-94m,Tc-95,Tc-96 radionuclides. No-carrier-added (nca) technetium radionuclides were separated from co-produced Nb-90.96 and bulk Zr employing liquid-liquid extraction with the help of anion exchanger trioctylamine (TOA) diluted in cyclohexane and HCI. Bulk Zr was monitored by spiking Zr-88,Zr-89 produced by 20 MeV proton induced reaction on Y-nat target. The optimum separation was achieved at 0.1 M TOA and 0.01 M HCl. Technetium radionuclides were recovered from the TOA phase by stripping with 0.1 M DTPA (diethylene triamine pentaacetic acid) dissolved in NaOH. (C) 2009 Elsevier Ltd. All rights reserved.
