METHOD FOR SEPARATION OF CHEMICALLY PURE OS FROM METAL MIXTURES

摘要

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.

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 any 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 OsO4 vapor comprising the at least one osmium isotope; distilling the OsO4 vapor out of the oxidizing solution to form a second solution comprising the Re-186 dissolved in the oxidizing solution; and separating the Re-186 isotope from the second solution.
