Chromatographic extraction with di(2-ethylhexyl)orthophosphoric acid for production and purification of promethium-147

Patent ·
OSTI ID:985400
A method of producing and purifying promethium-147 including the steps of: irradiating a target material including neodymium-146 with neutrons to produce promethium-147 within the irradiated target material; dissolving the irradiated target material to form an acidic solution; loading the acidic solution onto a chromatographic separation apparatus containing HDEHP; and eluting the apparatus to chromatographically separate the promethium-147 from the neodymium-146.
