Abstract
Carrier-free Au-199 produced in neutron activated platinum as a P-decay pro duct of Pt-199 has been separated from bulk matrices through liquid-liquid extraction (LLX) using the liquid cation exchanger, di-(2-ethylhexyl) phosp horic acid (HDEHP), as an extractant for the target element from an aqueous ammonia medium. The effect of octanol on the extraction was also studied. Production, extent of separation and purity of the radiotracers at differen t stages of their LLX separation have been verified by taking recourse to g amma-ray spectroscopy.
