| 中文摘要: |
| 从废钌催化剂中回收钌对于钌资源缺乏的我国具有特殊意义。基于文献和国内相关专利的分析，对氧化蒸馏法、熔融还原沉淀法、离子交换法、吸附法、捕集法、萃取法以及其他回收钌的方法进行了综述分析。不同方法各有其优缺点，其中成熟和应用最广的是氧化蒸馏法，选择性吸附法和萃取法具有选择性高、回收率高、污染小，是有发展前景的技术。 |
| 英文摘要: |
| It is of special significance to recover ruthenium from spent ruthenium catalysts in China. The sources of ruthenium-containing waste generally include waste catalyst, nuclear waste, alloy materials, and so on. Based on the literature and relevant domestic patents, several important methods to recover ruthenium from the waste catalysts are described. and the advantages and disadvantages ofeach method are also analyzed. These methods are oxidation distillation, melting reduction precipitation, ion exchange, adsorption, capture, extraction. Among them, oxidation distillation is the most mature and widely used. Selective adoption method and extraction method are promising, because they have the advantages of high selectivity, high recovery rate and low pollution. |
