Abstract
The retention and elution of Fe(III) on Dowex-50 cation exchange colum n in cone. HCl medium was studied using Fe-59 as a tracer. Details of the retention/elution behaviour of trace quantities of In-114m and Ga- 67 on Dowex-50 resin in the presence of various iron concentrations we re also studied since the iron content altered the adsorption behaviou r of Ga-67 and In-111 during chemical separation of these isotopes fro m irradiated target solutions. A method is reported to remove iron fro m the column by reduction of Fe(III) to Fe(II) on the Dowex-50 column itself with 1% NaI in cone. HCl or 0.1 N HCl and subsequent elution of the Fe(II) with conc. HCl. (C) 1998 Elsevier Science Ltd. All rights reserved.
