Abstract
Simultaneous production of carrier-free radioisotopes, 65Zn and 66,67,68Ga, has been achieved by activation of a thick copper target with a 50 MeV α-particle. A liquid-liquid extraction procedure for the effective separation of radionuclides 65Zn and 66,67,68Ga formed, respectively, through the nuclear reactions, ( α, p xn) and ( α, xn), from the target element has been developed in an aqueous hydrochloric acid medium using a liquid anion exchanger, trioctylamine (TOA), as an extractant. The extent of the separation and purity of the carrier-free radiotracers at different stages of their LLX separation has been verified by taking recourse to γ-ray spectrometry.
