Abstract:

Phosphorus removal by adsorbents has advantages of high efficiency and renewable adsorbents, and is considered an effective method for advanced phosphorus removal. Developing adsorbent materials with specific hydrogen bond acceptor functional groups, high complexation ability, and unique morphologies is an effective approach to enhance the phosphorus removal capacity and selectivity of adsorbents. The advantages, disadvantages, and adsorption characteristics of seven types of phosphorus removal materials, including metal (hydrogen) oxides, layered bimetallic oxides, metal organic frameworks(MOFs), natural/modified minerals, carbon-based materials, MXene, and polymers, were reviewed. Their commonly used synthesis methods were introduced. On this basis, the modification methods were summarized, including metal/metal oxide material modification methods and magnetic material modification methods. Additionally, the application prospects of machine learning in modification of phosphorus removal adsorbent materials had been summarized. Finally, the mechanism of selective phosphorus adsorption was discussed from three aspects: The acid-base characteristics of phosphate, the geometry of adsorbents, and the metal complexation ability. Future research directions for the preparation of high-selectivity phosphorus removal adsorbents were also prospected.

Key words: adsorption phosphorus removal, adsorbent materials, adsorption mechanisms

摘要:

吸附法除磷具有效率高、吸附材料可再生等优点,被认为是一种有效的深度除磷方法。开发具有特定氢键受体官能团、高络合能力和特殊形态的吸附材料,是提升吸附剂除磷能力及选择性的有效途径。综述了金属(氢)氧化物、层状双金属氧化物、金属有机骨架(MOFs)、自然/改性矿物、碳基材料、MXene、聚合物7种类型吸附除磷材料的优缺点和吸附除磷特性,并对其常用的合成方法进行介绍。在此基础上对其改性方法进行总结,包括金属/金属氧化物材料改性法和磁性材料改性方法,此外对机器学习在除磷吸附材料改性中的应用前景进行总结。最后从磷酸盐的酸碱特性、吸附剂的几何形状、金属络合能力3方面讨论了磷选择性吸附的机理,并对未来制备高选择性除磷吸附材料的研究方向进行了展望。
