Abstract
PURPOSE:To easily separate a Pt family metal from an electrode substrate by reducing the oxide of the Pt family metal coated on the substrate and treating the resulting metal with aqua regia so as to perfectly elute the metal. CONSTITUTION:The oxide of a Pt family metal or an active electrode substance contg. the oxide of a Pt family metal coated on an electrode substrate is reduced to the metal. The electrode is then treated with a mixed soln. contg. hydrochloric acid and nitric acid. The Pt family metal is perfectly eluted and separated from the electrode substrate.
