纳滤技术在盐湖卤水镁锂分离领域的研究进展

摘要

As a consuming country of the lithium resources in the world,China has used the lithium resources in greases,batteries,refrigerants and many other fields.Salt lake brine is rich in lithium resources,and the development of lithium resources from the salt lake brine will be of great significance.The present situation of lithium resources in China was briefly discussed,and the influences of the pore size of nanofiltration membrane and the mass transfer in nanofiltration process on the separation of the magnesium and lithium were analyzed.The research progress of the application of nanofiltration technology on the separation of the magnesium and lithium from salt lake brine was reviewed.The application prospect of nanofiltration technology on the separation of magnesium and lithium from salt lake brine was also put forward.%中国作为全球锂资源消费大国,已将锂资源广泛用于润滑脂、电池、制冷剂、药品等许多领域.中国的盐湖卤水中蕴藏着丰富的锂资源,因此对盐湖卤水锂资源的开发具有重要意义.简要介绍了中国锂资源现状;分析了纳滤膜孔径及纳滤膜中不同的传质过程对镁锂分离的影响;对纳滤技术应用于盐湖卤水镁锂分离的研究进展进行了综述,并对其应用前景进行了展望.
