摘要 |
<p>A hydrochloric acid solution containing platinum group metals has its acidity adjusted to 5.5 to 6.5M HCl and its redox potential adjusted to at least 500 mV, before being treated by chromatography. Particularly clean separation of at least Pt and Pd can be obtained, and recovered Pt and Pd of at least 99.99% purity may be obtained by following conventional precipitation processes.</p> |
