PROBLEM TO BE SOLVED: To provide a method for efficiently dissolving platinum chemically stable and uneasily dissolved, by using an electrolytic method. SOLUTION: In the electrolytic dissolution method, platinum is dissolved by being electrolyzed in an electrolyte by use of the platinum as an anode. The electrolyte is a 8-11.5 N hydrochloric acid solution. The platinum electrode is dissolved while being applied with electric current with a current density of 60-100 A/dm<SP>2</SP>at a liquid temperature of 60-80°C as an electrolyzing condition. The electrolyte further containing monoethanolamine as a complexing agent is preferable. COPYRIGHT: (C)2011,JPO&INPIT
