双氧水行业含钯废催化剂回收工艺的研究

摘要

The recovery process of palladium from spent hydrogen peroxide industry catalyst was investigated. By two steps hydrometallurgy process to achieve the enrichment of palladium, the enrichment was refined to obtain high purity palladium powder; the whole process of recovery was 98.66%. In addition, the key process was discussed, including sampling, remove organics and residue treatment, the optimized process was proposed on this basis.%对双氧水行业含钯废催化剂的回收工艺作了研究。采用湿法工艺分两步实现了钯的高效富集，富集物精炼得到99.95%的钯粉，全流程钯的回收率为98.66%。此外，对取样、除有机物、渣的处理等关键过程做了讨论，提出了优化的工艺流程。
