| titleOfInvention | Method for recovering noble metal from deactivated noble metal catalyst |
| abstract | The invention relates to a method for recovering noble metal from a deactivated noble metal catalyst, which comprises the following steps: dissolving the deactivated noble metal catalyst in a nonpolar solvent to obtain a first solution; adding an oxidant into the first solution to adjust the first solution into an alkaline solution, and fully reacting to obtain a second solution; and adding an aqueous solution of a reducing agent into the second solution, fully reacting, separating liquid, retaining an aqueous phase, and evaporating and crystallizing the aqueous phase to obtain the noble metal. The method for recovering the noble metal from the inactivated noble metal catalyst has simple process, does not need incineration treatment, and avoids organic complex sublimation of the noble metal caused by incineration in the traditional recovery method, thereby improving the recovery rate of the noble metal. |
