摘要:

近年来，随着稀土产量与需求之间的供需矛盾日益加深，对稀土资源的高效绿色提取和分离提出了更高的要求. 特别是从稀土矿选矿废水、精炼废水、海水和温泉等低浓度的稀土溶液中回收稀土资源已成为研究热点. 相比于蒸发结晶、化学沉淀、溶剂萃取等传统提取技术，吸附法因具有操作简单、成本低廉、处理量大和适应性强等优势，成为低浓度稀土深度回收的潜在方法之一. 本文汇总了近年来国内外有关于稀土离子吸附材料的研究进展，详细介绍了矿物基、碳基、金属−有机框架基和高分子基等吸附材料的设计与合成思路、微观形貌、吸附行为、材料性能和潜在的应用潜力. 最后，对比指出了各种吸附材料的优势和不足，提出开发面向应用的高效绿色靶向吸附材料是未来稀土吸附材料的主要发展趋势，靶向吸附技术也将成为低浓度稀土溶液（废水）资源化的主要方法，以期为稀土资源的高效利用提供参考.

Abstract:

Recently, with the persistently increasing demand and production of rare earth metals, the efficient and green recovery of rare earth resources has encouraged higher requirements. Particularly, the recovery of rare earth elements (REEs) from low-concentration rare earth solutions such as rare earth mineral processing wastewater, refining wastewater, seawater, and hot springs has become a research hotspot. Compared with conventional extraction methods, such as evaporative crystallization, chemical precipitation, and solvent extraction, adsorption holds promise for low-concentration rare earth recovery due to its advantages of simple operation, low cost, large treatment capacity, and strong adaptability. This paper meticulously outlines the recent research advancements on rare earth ion adsorption materials and introduces mineral-based, carbon-based, metal–organic framework (MOF)-based, and polymer-based adsorbents and their design ideas, microscopic morphologies (specific surface area, pore size, and particle geometric dimension), adsorption behaviors (adsorption kinetics and adsorption isotherm), material performances (maximum adsorption capacity, adsorption–desorption cycles, and stability), and potential applications (pH, dosage, coexisting competing ions, and actual REE wastewater treatment effect). Mineral-based adsorbent materials are characterized by clay minerals of layered silicate type; carbon-based adsorbent materials include biochar, graphene, and carbon nanotubes; MOF materials include the Zeolitic imidazolate framework (ZIF), University of Oslo (UIO), Materials of Institut Lavoisier (MIL), and Hong Kong University of Science and Technology (HKUST) series; polymer-based materials include natural and artificial polymers and hydrogels. Single-material adsorbents usually have low adsorption capacity, poor selectivity, and weak mechanical strength and are unstable under acidic conditions. To overcome these disadvantages, composite materials can be prepared, which capitalize on the benefits of their individual materials, e.g., use of polymer hydrogels loaded with fine-grained mineral materials to prevent agglomeration, in-situ MOF growth on the surface of graphene oxide to improve its stability in acidic conditions, use of polymers with specific functional groups that contain O, N, and P to alter porous materials to improve adsorption capacity, and magnetization modification of carbon-based materials and polymers to facilitate the subsequent recycling. Finally, the following future development trends of rare earth adsorbents are proposed: 1) development of green adsorbent materials, including green raw materials and no new pollution in the process, 2) development of highly selective adsorbent materials that can extract REEs from competing impurity ions and achieve the separation of a single rare earth among the REEs, and 3) development of high-efficiency adsorbent materials including REE extraction from low-concentration rare earth solutions and fast adsorption kinetics and their applications in the field of REE wastewater treatment.
