摘要： The invention includes a method of separating isotopes from a mixture containing at least two isotopes in a solution. A first isotope is precipitated and is collected from the solution. A daughter isotope is generated and collected from the first isotope. The invention includes a method of producing an actinium-225/bismuth-213 product from a material containing thorium-229 and thorium-232. A solution is formed containing nitric acid and the material and iodate is added to form a thorium iodate precipitate. A supernatant is separated from the thorium iodate precipitate and a second volume of nitric acid is added to the precipitate. The precipitate is stored and a decay product comprising actinium-225 and bismuth-213 is generated in the second volume of nitric acid which is then separated from the thorium iodate precipitate, filtered, and treated using at least one chromatographic procedure. The invention also includes a system for producing an actinium-225/bismuth-213 product.

摘要： A method of producing an adsorption medium to remove at least one constituent from a feed stream. The method comprises dissolving at least one metal compound in a solvent to form a metal solution, dissolving polyacrylonitrile into the metal solution to form a PAN-metal solution, and depositing the PAN-metal solution into a quenching bath to produce the adsorption medium. The at least one constituent, such as arsenic, selenium, or antimony, is removed from the feed stream by passing the feed stream through the adsorption medium. An adsorption medium having an increased metal loading and increased capacity for arresting the at least one constituent to be removed is also disclosed. The adsorption medium includes a polyacrylonitrile matrix and at least one metal hydroxide incorporated into the polyacrylonitrile matrix.
摘要翻译：一种生产吸附介质以从进料流中除去至少一种成分的方法。该方法包括将至少一种金属化合物溶解在溶剂中以形成金属溶液，将聚丙烯腈溶解在金属溶液中以形成PAN-金属溶液，并将PAN-金属溶液沉积到骤冷浴中以产生吸附介质。通过使进料流通过吸附介质，从进料流中除去至少一种成分，例如砷，硒或锑。还公开了具有增加的金属负载和增加用于阻止待除去的至少一种成分的能力的吸附介质。吸附介质包括聚丙烯腈基质和掺入聚丙烯腈基质中的至少一种金属氢氧化物。
