<p>PROBLEM TO BE SOLVED: To provide a method by which platinum-group metals can be separated clearly from each other by using a chromatography medium. SOLUTION: The platinum-group metals are separated from each other by using a glycol methacrylate chromatography medium and a reduced supplied raw material. At the time of separating the metals from each other, iridium, rhodium, and ruthenium are simultaneously eluted and, thereafter, palladium, platinum, and osmium are eluted in this order. The iridium and rhodium can be separated from each other by another method.</p> |
