Recovery of precious metals from acid solutions by N-containing electroactive polymers |
摘要 |
The present invention is directed to a process for reducing the oxidation state of a metal by contacting an acidic solution of the metal with an electroactive polymer, and accumulating and recovering the metal. More particularly, the invention is directed to a method for recovering precious metals like gold, platinum, palladium, and gold-platinum alloys from acidic solution by contacting the solution with an electroactive polymer like polyaniline or polypyrrole.
