Our aim was to obtain and isolate the carrier-free gamma emitter, 54Mn. Manganese-54 was
produced via cyclotron activation in the 51V(a,n)54Mn
reaction, and separated from HCl solution on Dowex-50 ´ 8 resin.
The effectiveness of chemical separation was checked using the internal tracer 48V,
produced in a cyclotron via the natTi(p,xn)48V reaction.
The microcomponent 54Mn was eluted from the column with 3 M HCl, and vanadium with a
0.1 M HCl/ethanol/H2O2 mixture. The pair Ti/48V was separated on
Dowex-50 ´ 8, using 0.03 M HClO4 as the eluent for 48V
and 1 M HClO4 for natTi. The carrier-free 54Mn was of 99.9%
radionuclide purity. In separation of the carrier-free pair 54Mn/48V,
the recovery yield was 98.7% for 54Mn and 96.4% for 48V.
