Rhodium acetate is widely used in the field of catalysts, but the process of recycling rhodium acetate may not be well known to many. Since we’re on the subject, in this issue, I will talk about the recycling of rhodium acetate.

Precious Metal Recycling
In industrial production, rhodium acetate is generally in a solution form, which is much easier to handle than powders. We directly extract rhodium from these rhodium-containing solutions through precise chemical reactions. Rhodium reacts with nitric acid to form soluble rhodium compounds, while other impurities are not so easily dissolved.

Next is the precipitation of rhodium. We add hydrochloric acid, as it reacts with

the purified rhodium compound to produce a rhodium salt that is insoluble in water. Thus, rhodium precipitates out of the solution. After precipitation, the next steps are drying and calcination; first, the material is dried to remove moisture. Then, the dried rhodium salt is processed in a high-temperature environment to remove residual organic substances, ultimately yielding pure rhodium.

This concludes our discussion on the recycling of rhodium acetate. I hope this has been helpful and look forward to progressing together in the journey of precious metal recycling.
