An anion exchange radiochemical experiment: Separation of manganese, zinc, and iron

Abstract

Radiochemical ExperimentColumbus I Separation o f manganere, zinc, a n d iron A number of ion exchange experiments employing radio isotopes have been suggested in the literature (1-3). In many of these the student is required to collect fractions in planchets and dry these before counting the activity.I<raus and Nelson list several important advantages for the separation of metal complexes by anion exchange as compared to the separation of metals by cation exchange (4).

General chemistry demonstrations based on nuclear and radiochemical phenomena

“…The separation of Mn, Zn, and Fe has been reported (24) in a procedure using the exchanger Dowex 2-X8 (200-400 mesh). The appropriate activities here are HMn (324 da, 0.835 MeV 7), 65Zn (245 da, 1.11 MeV 7) and 69Fe (45 da, 0.46 and 0.27 MeV 8, 1.10 and 1.29 MeV 7).…”
