METHOD OF ENTRAPPING AND BONDING RUTHENIUM IN GASEOUS FORM |
摘要 |
<p>Process for trapping gaseous ruthenium on polyvinylpyridine, usable in particular for recovering the radioactive ruthenium originating from irradiated nuclear fuels. This process consists in bringing a gas containing ruthenium in gaseous form into contact with an adsorbent (11b) consisting of a vinylpyridine polymer or copolymer to bind the ruthenium onto the latter. The gas may consist of the vapours originating from a concentrate of fission products containing ruthenium which has been heated (in 31) in the presence of an oxidising agent to volatilise the ruthenium. <IMAGE></p> |
