摘要
采用直接溶解贵金属的方法来回收废旧钯炭催化剂中的钯,提出两阶段回收钯粉的新工艺,较之传统工艺流程短、环境友好、金属回收率高。给出了最佳工艺参数,钯的回收率可达99.98%,纯度达99.97%。
The method of dissolving precious metals from spent catalyst is used to recover palladium from spent Pd/C catalyst.A clear and simple two-step technique with higher recovery efficiency than traditional technique is utilized.The optimum process is obtained.Palladium power is produced with purity of 99.97%,recovery efficiency of 99.98%.
