Refining impure platinum@ in electrolytic cell - using PTFE membrane as a cation exchange membrane

摘要

Electrowiring of high purity Pt from solutions of Pt contaminated with noble and non-noble metals, consists of using a teflon membrane as cation exchange membrane in a cell employing a voltage of 2.5-8V and a current density of 0..3-12.5 A.dm2. USE/ADVANTAGE - Refining waste Pt material contaminated with Rh, Pd, Ir, An, As, Cu, Fe, La, Ni, Sb, As Pb, Cd, Al, Mn, Mo, Si, Zn, Sn, Zr, W, Ti, Cr. Cost of appts. and process time is low with high parts Pt produced.
