| 摘 要： | 通过对稀王水控量溶解钯的条件、活性钯粉的还原条件、硝酸溶解钯的条件研究，解决了部分钯粉不能完全溶解的困难，建立了活化-溶解法规模化生产硝酸钯的工艺条件。对活化前后钯粉的粒度、比表面积和表面形貌分析的结果表明，活化后钯粉颗粒变小，表面积增大，扫描电镜显示，活化后钯粉粒径变小，呈海绵状，钯的溶解活性提高，有利于钯粉的完全溶解。 |
| 关 键 词： | 无机化学 钯粉 溶解活性 硝酸钯 规模化生产 |

| Abstract: | An activation-dissolution method has been establishedtoproducepalladium nitrate in a large scale from palladium powder. Palladium powder was activated by treatment with aqua regia and then by reduction with hydrazine hydrate. The activated palladium powder could be completely dissolved in nitric acid, which greatly facilitates a large-scale production of palladium nitrate. The activation mechanism was investigated by comparing the changes in the particle size, specific surface area and surface structure of palladium powder before and after activation. Palladium powder particles diminished and the surface area increased after activation, which led to an acceleration of the dissolution process. |
| Keywords: | inorganic chemistry palladium powder dissolution activity palladium nitrate large-scale production |
