B. Liu et al., PREPARATION OF CARRIER-FREE GROUP TRACERS FROM A GOLD TARGET IRRADIATED BY HIGH-ENERGY HEAVY-IONS, Journal of radioanalytical and nuclear chemistry, 223(1-2), 1997, pp. 3-7
Radioisotopes of 37 elements were isolated from a gold target irradiat
ed with an energetic C-12 beam and were used as a multitracer to estab
lish procedures for separating themselves into groups of carrier-, sal
t- and organic matter-free tracers. solvent extraction with HDEHP and
ethyl methyl ketone along with cation exchange yielded group tracers r
eady for application to chemical and biological studies.
