摘　　要：过量的磷流入水体易导致水体富营养化等环境问题。吸附法由于操作方便、经济高效等特点被广泛应用于水体磷酸盐的去除。有序多孔材料具有孔道规则,比表面积大,孔容大等特点,其作为载体可有效提高活性物种的分散性,从而提高吸附剂去除磷酸盐的效率。该文综述了基于不同有序多孔材料合成的吸附剂应用于水体磷酸盐去除的进展,主要包括有序多孔碳材料、有序多孔硅材料和金属有机框架。讨论了基于有序多孔材料吸附剂的磷酸盐吸附性能、主要吸附机制、影响因素及回收利用等。总结了基于有序多孔材料吸附剂吸附磷酸盐存在的问题,展望了其未来研究方向及应用前景。Excess phosphorus discharge into water body leads to environmental problems such as eutrophication.Adsorption method has been extensively used in phosphate removal from water due to its advantages of economy,convenience,and efficiency.Ordered porous materials,with the characteristics of regular channels,large specific surface area and large pore volume,can effectively improve the dispersity of active species when being used as carrier,thus improve the phosphate removal efficiency of adsorbents.Herein,recent progress on ordered porous materials,especially ordered porous carbon materials,ordered porous silicon materials and metal organic frameworks,as sorbents for phosphate removal from water was summarized.The phosphate adsorption performance,main adsorption mechanism,influence factors,and recycle of adsorbents based on ordered porous materials were then discussed.Finally,The existing problems,the future research and application directions of phosphate adsorption by adsorbents based on ordered porous materials were analyzed and proposed.
