| Research Abstract |
In order to develop a new extraction system for rhodium and ruthenium in hydrochloric acid solution, we performed analyses of metal extraction mechanism and structure optimization of new extractants for practical use. Structural analyses of rhodium chloro complexes with amide-containing tertiary amide extractants by X-ray absorption fine structure and small angle neutron scattering methods suggested that the extractants interact with the rhodium chloro complex in the outer-sphere of the rhodium ion. The most practical extractant among the studied compounds was N-2-ethylhexyl-bis(N,N-di-2-ethylhexyl-ethylamide)amine.
