The electrochemical aqueous reduction (EAR) method is studied for the recovery of precious metals from solutions typical in hydrometallurgy. In the first step, multivalent metal ions are reduced after which they spontaneously react with precious metal ions also present in the solution, resulting in the deposition on the electrode. The EAR mechanism and the deposit composition and morphology are studied with cyclic voltammetry, electrochemical quartz microbalance, and SEM-EDX. The results show that homogenously distributed Au or Pt nanoparticles can be deposited on the glassy carbon, ready for use in applications like catalysis.

摘要

The electrochemical aqueous reduction (EAR) method is studied for the recovery of precious metals from solutions typical in hydrometallurgy. In the first step, multivalent metal ions are reduced after which they spontaneously react with precious metal ions also present in the solution, resulting in the deposition on the electrode. The EAR mechanism and the deposit composition and morphology are studied with cyclic voltammetry, electrochemical quartz microbalance, and SEM-EDX. The results show that homogenously distributed Au or Pt nanoparticles can be deposited on the glassy carbon, ready for use in applications like catalysis.
