Title:
METHOD AND APPARATUS FOR PLATINUM RECOVERY
Document Type and Number:
Japanese Patent JP2014185366
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for recovering platinum safely, easily and economically with reduced environmental load.SOLUTION: A method of recovering platinum comprises applying a voltage between the platinum and a counter electrode 24 in a state where a platinum source 11 containing to-be-recovered platinum and the counter electrode 24 are immersed in an electrolytic solution containing hydrogen peroxide and a metal ion and controlling the electric potential of the platinum between 0.1 V and 1.5 V, with respect to the reversible hydrogen electrode, to dissolve platinum in the electrolytic solution and causing the platinum dissolved in the electrolytic solution to undergo reduction precipitation on an action electrode 31 immersed in the electrolytic solution.
