| 中文摘要: |
| 以氧化铝为载体的某含钯废催化剂为原料，采用盐酸介质中添加氧化助浸剂的方案对钯选择性浸出，并考察了焙烧，还原，浸出过程的适宜工艺条件。结果表明，钯的回收率可以达到98%以上。 |
| 英文摘要: |
| Palladium was recovered from spent alumina-supported catalyst by the process of selective leaching using hydrochloric acid with an oxidant. The optimized conditions of roasting, reduction, leaching processes were also investigated. The results showed that the palladium recovery ratio was over 98% in the optimum condition. |
