dc.description.abstract
The radiochemical effects of thermal neutron capture in tris(2,2,6,6-tetramethyl-3,5-heptandionato)chromium(III) (Cr(tmhd)₃) were investigated. A method was devised to quantify the amount of the induced ⁵¹Cr activity recoverable in the original chemical form and to confirm that it is indeed Cr(tmhd)₃. The method is based on a combination of chemical separation (column chromatography and recrystallization) and analytical (radio-TLC, HPLC, and gamma spectrometry) techniques. Cr(tmhd)₃ samples were irradiated and purified in two steps after irradiation. We found that two of the (three) purification pathways yielded good agreement among final ⁵¹Cr activity concentrations. The corresponding samples appeared to be of exceptional radiochemical purity.
