Abstract
Official abstract text for this publication.
A method for separating an amount of osmium from a mixture containing the osmium and at least one other additional metal is provided. In particular, method for forming and trapping OsO4 to separate the osmium from a mixture containing the osmium and at least one other additional metal is provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of producing an amount of chemically pure Re-186 isotope, comprising: irradiating a metal target comprising an amount of isotopically enriched osmium isotope consisting of Os-189, Os-192, or a combination thereof in a thermal proton flux to form a mixture comprising at least one osmium isotope and at least one additional metal comprising the Re-186 isotope; contacting the mixture with an oxidizing solution to form a volatile OsO 4 vapor comprising the at least one osmium isotope; distilling the OsO 4 vapor from the oxidizing solution to form a second solution comprising the Re-186 isotope dissolved in the oxidizing solution; and separating the Re-186 isotope from the second solution. 2. The method of claim 1 , wherein the Re-186 isotope is separated from the second solution using a method selected from the group consisting of contacting the second solution with a reducing agent, contacting the second solution with a chromatographic column, and electroplating the at least one metal from the second solution. 3. The method of claim 2 , wherein the Re-186 isotope is separated from the second solution by contacting the second solution with an alumina chromatographic column and eluting the Re-186 with a saline solution.
