Carrier-free separation of (115m)In from irradiated Cd by solvent extraction with 1-phenyl-3-methyl-4-caproylpyrazolone-5.
A method is presented for the routine milking of the 41 2 -hr half-life nuclide (115m)In from its 2.3 day half-life parent (115m)Cd. The method utilizes the extraction of In and Cd from aqueous solution at various pH values, 1-phenyl-3-methyl-4-caproylpyrazolone-5 in isobutyl methyl ketone being used as extracting agent. A good decontamination factor was obtained and the yield of (115m)In from residual cadmium activity was 85-90%.
