| Abstract: | The paper described the process method of recovering the metal palladium from waste TDI hydrogenation catalyst. By burning and accumulating, impurity cleaning purifying, the recovering rate of palladium is up to 98%, the product purity reached the national standardQdPd-2,Pd%≥99. 95%）. |
| Keywords: | waste TDI hydrogenation catalyst palladium recovering |
