Outline of Final Research Achievements

In order to develop effective extraction systems for rhodium in hydrochloric acid solution by using a synergistic effect, we investigated the extraction mechanism of rhodium in mixed solvent systems of sulfide-type and amine-type extractants. We analyzed the distribution behavior of rhodium between the organic extractant phase and hydrochloric acid solution, and the structure of the rhodium complexes extracted. As a result, the synergistic effect would stem from neutralization of a rhodium complex anion with the protonated amine-type extractants and substitution of the coordinated water of the rhodium by the sulfide-type extractant.
