| 中文摘要: |
| 纯度大于99.999%的高纯铂广泛用于电子工业等领域，且需求量越来越大。介绍了高纯铂制备技术研究现状，并对主要制备技术存在的优缺点进行了评述。现有的铵盐沉淀法、氧化水解法、氧化载体水解法、离子交换法和萃取法等都不同程度地存在铂纯度低、流程长、直收率低以及环境污染等问题。未来还需深入研究铂溶液体系中贱金属杂质元素及相似元素的赋存状态等特性，合理设计除杂顺序，开发出高纯铂高效清洁制备技术。 |
| 英文摘要: |
| High purity platinum with a purity greater than 99.999% is widely applied in electronic industry and other fields, and the demand is increasing. The preparation technologies of high purity platinum were introduced, and the advantages and disadvantages of main preparation technologies were reviewed. The existing ammonium salt repeated precipitation, oxidation-hydrolysis, oxidation carrier hydrolysis, ion exchange and extraction methods all have different levels of low purity, long process, low direct yield and environmental pollution issues. It is necessary to develop high efficient and clean preparation technology of high purity platinum by studying the characteristics of base metal impurities and similar elements in the platinum solution system, designing the reasonable order of removing impurities and shortening the process flow in the future. |
