概要

• 論文の詳細を見る

• The separation and purification of <SUP>227</SUP>Ac, <SUP>227</SUP>Th, <SUP>223</SUP>Ra, and <SUP>223</SUP>Fr were studied by the solvent extraction method using HDEHP (bis(2-ethylhexyl)phosphoric acid) as an extractant. The mutual separation of Ac, Th, and Ra was achieved, and new milking processes for <SUP>223</SUP>Fr and <SUP>228</SUP>Ac are presented.
