摘要
吸附法是从复杂基体中分离和富集锂的最有效方式,而高效锂吸附剂是吸附提锂的技术核心。综述了氢氧化铝基吸附剂、铝盐吸附剂、锰系离子筛型吸附剂及钛系离子筛型吸附剂等的吸附机理、原料、制备方法、掺杂、复合及吸附性能,分析了锂吸附剂的特点及应用前景,并梳理了粉末状吸附剂的现有成型技术,也对锂吸附剂存在问题及发展方向做了展望,以期为改进吸附剂性能、推动盐湖提锂行业发展提供参考。
The adsorption method is the most effective way to separate and enrich lithium from complex matrices,and efficient lithium adsorbents are the core of lithium adsorption technology.In this article,the adsorption mechanism,raw materials,preparation methods,doping,composite and adsorption performance of aluminium hydroxide-based adsorbents,aluminium salt adsorbents,manganese-based ion sieve adsorbents and titanium-based ion sieve adsorbents are reviewed,and the properties and application prospects are analysed.Existing powder adsorbent shaping technologies are also summarised,and the problems and development directions of lithium adsorbents are also discussed.The purpose of the above is to provide a reference for improving the performance of adsorbents and promoting the development of the salt lake lithium extraction industry.
