Research progress on the adsorption and recovery of gallium in alkaline solutions
综述了碱性体系中回收镓的吸附材料研究进展,重点关注树脂基、聚合物基、无机-有机复合、生物质基及金属-有机框架(MOFs)基5类材料。通过分析其官能团设计(如偕胺肟基、酚羟基)与结构调控策略,对比了各类材料在吸附容量、选择性和耐碱稳定性方面的性能,并阐述了其构-效关系与作用机制。最后,分析了已有材料在强碱、高铝环境下吸附回收镓面临的挑战,并对未来高性能吸附剂的定向开发方向进行了展望,以期推动镓回收技术的工业化应用。
This review summarizes recent advancements in adsorbent materials for gallium recovery from this system,focusing on five categories:resin-based,polymer-based,inorganic-organic composite,biomass-based,and metal-organic framework (MOF)-based materials.By analyzing functional group design (e.g.,chelating oxime groups,phenolic hydroxyl groups) and structural regulation strategies,the performance of various materials in adsorption capacity,selectivity,and alkali stability is compared.Their structure-activity relationships and mechanisms of action are elucidated.Finally,challenges faced by existing materials in gallium adsorption and recovery under strong alkaline and high-aluminum conditions are analyzed.Future directions for the targeted development of high-performance adsorbents are proposed to advance the industrial application of gallium recovery technology.
