Platinum recovery methods

The present invention is directed to a method for recovery of platinum from a coating on a component, wherein the coating includes platinum aluminide, the method including: contacting the coating on the component with a reagent solution, the reagent solution including a reactive species capable of solubilizing an aluminum salt in water, which results in formation of a platinum-rich residue on thecomponent; separating the platinum-rich residue from the component; and collecting the platinum-rich residue. The reactive species may be hexafluorosilicic acid. 本发明涉及用于从部件上的涂层中回收铂的方法，其中涂层包括铝化铂，该方法包括：使部件上的涂层与试剂溶液接触，该试剂溶液包括能够使铝盐溶解于水中的反应性物种，这导致在部件上形成富含铂的残余物；从部件分离富含铂的残余物；并且收集富含铂的残余物。反应性物种可为氟硅酸。
