摘　　要：锂锰氧化物离子筛对Li+离子选择性高,吸附容量大且环境友好,被认为是目前最具应用前景的绿色盐湖卤水提锂方法。重点介绍了我国盐湖锂资源的情况及λ-MnO2离子筛盐湖提锂的反应机理、制备方法以及研究现状,并对我国盐湖卤水的开发提出了自己的看法。Lithium manganese oxide ion-sieve is considered as the-most prospective technology for recovery of lithium from salt lake brine on account of its high selectivity, high capacity of adsorption for Li+ and friendly environment. In this paper, the lithium resource of salt lake, the current research status, reaction mechanism and synthesis method on recovery of lithium hy λ-MnO2 ion-sieve from salt lake are pointedly introduced. Future trend of exploitation from salt lake brine in China is also discussed.
