| 中文摘要: |
| 溶剂萃取法分离提纯铂相比于传统的沉淀法具有工艺简单、高效、操作安全等优势，本文从胺类萃取剂、中性磷类萃取剂、离子液体萃取剂、新型萃取剂四个方面综述了近年来溶剂萃取分离铂的技术研究进展，并对各种溶剂萃取法存在的优缺点进行了评述。胺类萃取剂和中性磷类萃取剂萃取效率高，成本低，已成熟应用于铂的分离提纯，但选择性相对较差。离子液体的研究起步较晚，其选择性好但造价高昂，距离工业化应用还有很长的距离。随着对铂分离提纯技术的要求越来越高，进一步开发高效清洁的新型萃取剂、研究协同萃取体系、简化萃取流程以及改进萃取设备是未来铂萃取分离技术的发展方向。 |
| 英文摘要: |
| Separation and purification of platinum by solvent extraction have many advantages, such as simple process, high efficiency and safe operation. This article reviews the progress in the solvent extraction method of platinum using four different extractants which are amine, neutral phosphorus and ionic liquid and novel extractant. The advantages and disadvantages of these extractants are also discussed. Owing to their advantages of high extracting capacity and low cost, amine and neutral phosphorus extractant have been widely applied to the purification and separation of platinum, but their selectivity is relatively poor. The research of ionic liquids started late. Although the selectivity of ionic liquids is better, high cost remains a problem. Therefore, there is still a long way to go before their industrial application. With the increasing requirements for better platinum separation and purification technology, the future development should focus on exploiting efficient and clean novel extractant, exploring synergistic solvent extraction, simplifying process and improving extraction equipment. |
