摘　　要：过量的磷流入水体会引起水体富营养化,去除水体磷酸盐对缓解水体富营养化具有重要意义。在除磷方法中,吸附法具有成本低、操作简单、处理效果好等优点。将锆运用到吸附材料中,可以提高其对磷酸盐的吸附性能。综述了近年来关于锆基吸附剂去除水体中磷酸盐的研究进展,包括锆氧化物/氢氧化物、锆基碳材料、锆基黏土材料、锆基生物质材料和其他锆基材料,其吸附机理、吸附容量、pH值与回收情况等也进行了相应的讨论。总结了锆基吸附剂吸附磷酸盐存在的问题,展望了其未来研究方向。Excess phosphorus from wastewater discharged into natural water will lead to eutrophication.It is necessary to remove phosphate from water before its discharge into natural waters.Among the phosphorus removal methods,adsorption method has been extensively studied due to its low cost,simple operation and good treatment effect.The application of zirconium in adsorption materials can improve its adsorption performance for phosphate.The recent progress in the application of zirconium based adsorbents in the removal of phosphate from water is summarized,such as zirconium oxide/hydroxide,zirconium based carbon materials,zirconium based clay materials,zirconium based biomass materials and other zirconium based materials.The adsorption mechanism,adsorption capacity,pH value and adsorbent recovery are also discussed.The problems of phosphate adsorption by zirconium based adsorbents are summarized,and the future research direction are also proposed.
