Radiometric Studies on Adsorption of Iron on Cation Exchange Resin and also of Indium and Gallium in Presence of Iron: Applicability to Prepare ↑(67)Ga with Low Iron Content

摘要

The retention and elution of Fe(Ⅲ)on Dowex-50 cation exchange column in conc. HCl medium was studied using ↑(59)Fe as a tracer. Details of the retention/eltion behaviour of trace quantities .of ↑(114m)In and ↑(67)Ga on Dowex-50 resin in the presence of various iron concentrations were also studied since the iron content altered the adsorption behaviour of ↑(67)Ga and ↑(111)In during chemical separation of these isotopes from irradiated target solutions. A method is reported to remove iron from the column by reduction of Fe(Ⅲ) to Fe(Ⅱ) on the Dowex-50 column itself with 1% NaI in conc. HCl or 0. I N HCl and subsequent elution of the Fe(II) with cone, HCl. #1998 Elsevier Science Ltd. All rights reserved
