Liquid-liquid extraction of α-activation products of iron with HDEHP

The carrier-free radiotracers, Mn-52,Mn-56 Co-55,Co-56,Co-58 and Ni-56,Ni-57 were produced simultaneously by accelerated a-particle activation of iron. They were subsequently studied through LLX using the liquid cation exchanger HDEHP, as an extractant. A considerable enrichment of individual carrier free radionuclides of manganese, cobalt and nickel was achieved. Production and verification of purity of the carrier-free radiotracers at different stages of their extraction were carried out by gamma-ray spectroscopic studies.
