Title: Uptake of arsenic and selenium on iron-doped Pb resin

Journal Article · · Journal of Radioanalytical and Nuclear Chemistry

We report the uptake of the radioisotopes 73As and 75Se was characterized on Fe3+-doped Pb resin (Eichrom Technologies) from pH 1 to 12. There is good uptake of arsenic and selenium over a wide pH range (~ 1 to 10) with a decrease only at high pH (~ 12). Column experiments were performed to demonstrate the separations of these elements from solutions with near neutral pH values (~ 6 to 8) with high yields and high radiopurity. These separations may be relevant for a wide variety of applications especially isotope harvesting research.
