Abstract[English]
A method of recovering a platinum group metal from a catalyst coated membrane, the method comprising: incinerating a catalyst coated membrane to produce a platinum group metal containing ash; treating the platinum group metal containing ash with hydrochloric acid and an oxidant to leach the platinum group metal from the ash and produce a platinum group metal solution without smelting of the ash; and separating the platinum group metal solution from the ash.[French]
