CHROMATOGRAPHIC METHOD OF SEPARATING RUTHENIUM FROM PLATINUM GROUP METALS |
| 摘要 |
<p>A chromatographic separation method separates ruthenium from other platinum group metals in a feed solution, by converting the Ru to a nitrosyl complex, retaining the nitrosyl complex temporarily on the chromatography column and subsequently eluting Ru, for example using an oxidising or reducing eluent. Fig 1 shows the elution profile obtained from a mixture of Rh chlorocomplexes (Peak 1) and Ru nitrosyl species (Peak 2).</p> |
