Enriched 146Nd recovery from a 147Pm production process by applying ion imprinting technique

A neodymium-imprinted polymeric sorbent was synthesized to recover the enriched 146 Nd-target material from 147 Pm production process. The studies indicated the neodymium (III) adsorption capacity of 1.5 mg g − 1 . 146 Nd-oxide was irradiated in Tehran Research Reactor to produce 147 Pm. Then, the p...

Description
Summary:A neodymium-imprinted polymeric sorbent was synthesized to recover the enriched 146 Nd-target material from 147 Pm production process. The studies indicated the neodymium (III) adsorption capacity of 1.5 mg g − 1 . 146 Nd-oxide was irradiated in Tehran Research Reactor to produce 147 Pm. Then, the prepared Nd-selective sorbent was applied to recover the macro-gram amounts of 146 Nd from a micro-gram amount of 147 Pm. Regarding the high efficiency of leaching process (> 96%), the remaining natural Nd-ions trapped in polymer structure caused an acceptable slight down-blending of the target material. The sorbent with 146 Nd was burned with a heat-gun to produce 146 Nd 2 O 3 for the next experiments.
