摘要
近年来,随着锂电池技术和电动汽车的快速发展和大规模应用,锂资源的市场需求呈现出急剧增长的态势,矿石锂和卤水锂资源开发产量已无法满足市场需求。从地表盐湖卤水、深层卤水等液态资源中提锂具有巨大的市场开发潜力,是当前锂资源开发的重要研究方向。吸附法适用于我国低浓度大体积卤水中锂的提取,而锂离子选择性吸附材料是吸附提锂的核心。本文综述了有机(冠醚)、无机(铝基、锰基和钛基)以及复合型选择性锂吸附材料的制备方法、吸附性能和吸附机理,为研究新型锂吸附材料、克服材料缺陷以及改进吸附剂性能提供参考,以期推动盐湖卤水锂资源高效提取利用的进一步发展。
In recent years,with the rapid advancement and large-scale application of lithium battery technology and electric vehicle,the market demand for lithium resource is growing sharply.However,due to insufficient mining degree and extraction technology,the total production capacity of ore lithium and brine lithium resources is far below the actual market demand.Extracting lithium from surface salt lake brine,deep brine and other liquid resources has the advantages of large resource potential and low extraction cost,which presents an important research direction in the lithium resource extraction field.Among available lithium extraction technologies,adsorption method is suitable for extracting lithium from low concentration and large volume liquid brine resources in China,and selective lithium ion adsorption materials are the core of adsorption method.In this review,we focus on the preparation and application of lithium ion selective adsorption materials for lithium extraction from brine.The preparation methods,adsorption properties and adsorption mechanisms of organic(crown ether),inorganic(aluminum-,manganese-and titanium-based adsorbents)and composite selective lithium adsorption materials are reviewed.This review provides a brief prospect for the design and development of new lithium adsorption materials,which may push forward the efficient extraction and utilization of lithium resources from salt lake brine.
