PROBLEM TO BE SOLVED: To provide a method for effectively dissolving platinum which is chemically stable and is not easily dissolved, by an electrolytic process. SOLUTION: The method for electrolytically eluting platinum includes electrolyzing an electrolytic solution while using platinum as an electrode to elute platinum of the electrode. The electrolytic solution is a solution of 5-15 wt.% sodium hydroxide, which contains 3-10 wt.% monoethanol-amine as a complexing agent. The electrolytic condition includes applying an alternating current with a current density of 100-140 A/dm<SP>2</SP>at a liquid temperature of 25-60°C. COPYRIGHT: (C)2011,JPO&INPIT |
