摘　　要：锂资源作为国民经济和国防建设的重要战略性资源,在锂电池、玻璃和陶瓷、润滑脂、空调、连铸轧、聚合物、制药、铝冶炼等领域具有重要的作用。目前我国的锂消费量占据全球的60%左右,锂资源大多分布在西部的盐湖卤水中,普遍存在低锂浓度、高镁锂比等问题。传统的盐湖卤水提锂方法普遍存在能源消耗高、环境污染严重和工艺复杂等困难。金属有机骨架(MOFs)材料是一种新兴的多孔材料,其结构具有多样性、可调节性和超高的比表面积,由于这些特性,在许多领域显示巨大的应用前景,尤其在卤水中选择性分离提取锂资源领域处于一个新兴的热点。文章对近年来金属有机骨架(MOFs)材料从卤水中提锂的进展作出了总结,并对MOFs材料在卤水提锂方面的前景进行了展望。As a critical strategic resource,lithium plays an essential role in various sectors including lithium batteries,glass and ceramics,lubricating grease,air conditioning,continuous casting,rolling,polymers,pharmaceuticals,and aluminum smelting.When dealing the salt lake with high magnesium-tolithium ratios,traditional methods of lithium extraction from brines always inevitably cause problems such as high energy consumption,severe environmental pollution,and process complexity.Metal-Organic frameworks(MOFs)are emerging porous materials with structural diversity,adjustability,and ultra-high specific surface area,which show great application prospects in many fields due to these characteristics,especially in the selective separation and extraction of lithium resources from brine in an emerging hot spot.This paper provides a comprehensive summary of recent progress in the extraction of lithium from brine using metal-organic frameworks(MOFs).It also offers insights into the potential of MOF materials in revolutionizing the process of lithium extraction from brine,highlighting their prospect in addressing the existing challenges of efficiency,environmental impact,and process simplification.
