摘　　要：从废水中去除磷是控制水体富营养化的重要途径.在除磷方法中,吸附法具有设计简单和操作简便、成本低等优点.而锆因其通过路易斯酸碱相互作用和内球络合作用对磷酸盐具有优异的结合能力,加之其在碱性条件下易于再生、环境兼容性好、在广泛pH范围内的低溶解度以及良好的抗氧化性能,已成为一种极具潜力的除磷吸附剂,当前已有大量研究通过锆改性吸附材料以增强其对磷酸盐的吸附性能.系统梳理了近年来锆改性吸附剂去除水体中磷酸盐的研究进展,综述了诸如锆氧化物/氢氧化物、锆基金属氧化物材料、锆基碳材料、锆基金属有机骨架材料以及锆改性粘土材料等多种锆改性吸附剂,详细探讨了此类吸附剂的磷酸盐吸附容量、影响吸附效能的关键因素以及吸附机理.在未来的研究中,应考虑锆改性复合材料吸附剂在复杂条件下的稳定性和潜在风险,以及其高效分离和再生的能力.Phosphates removal from wastewater is a critical approach for controlling eutrophication in water bodies.Among various phosphate removal technologies,adsorption stand out due to their advantages of simple design,ease of operation,and low cost.Zirconium has become a promising adsorbent for phosphorus removal due to its excellent phosphate binding ability through Lewis acid-base interaction and endospheric complexation,easy regeneration under alkaline conditions,good environmental compatibility,low solubility in a wide pH range,and good oxidation resistance.At present,there have been a lot of studies on modifying zirconium adsorption materials to enhance their phosphate adsorption properties.Herein,the recent research progress on zirconium-modified adsorbents for removing phosphates from aquatic environments was systematically summarized,and a variety of adsorbents such as zirconium oxides/hydroxides,zirconium-based metal oxide materials,zirconium-containing carbonaceous materials,zirconium-based metalorganic framework(MOF)materials,as well as zirconium-modified clay materials were reviewed.The phosphate adsorption capacity of these adsorbents,key factors influencing their adsorption efficiency,and the underlying adsorption mechanisms were discussed in detail.In future studies,the stability and potential risks of zirconium-modified composite adsorbents under complex conditions,as well as their ability to efficiently separate and regenerate,should be considered.
