Rapid urban industrialization and agricultural production have led to the discharge of excessive phosphate into aquatic systems, resulting in a rise in water pollution. Therefore, there is an urgent need to explore efficient phosphate removal technologies. Herein, a novel phosphate capture nanocomposite (PEI-PW@Zr) with mild preparation conditions, environmental friendliness, recyclability, and high efficiency has been developed by modifying aminated nanowood with a zirconium (Zr) component. The Zr component imparts the ability to capture phosphate to the PEI-PW@Zr, while the porous structure provides a mass transfer channel, resulting in excellent adsorption efficiency. Additionally, the nanocomposite maintains more than 80% phosphate adsorption efficiency even after ten adsorption-desorption cycles, indicating its recyclability and potential for repeated use. This compressible nanocomposite provides novel insights into the design of efficient phosphate removal cleaners and offers potential approaches for the functionalization of biomass-based composites.
快速的城市工业化和农业生产导致过量的磷酸盐排放到水体系统中，造成水污染加剧。因此，迫切需要探索高效的除磷技术。在此，通过用锆（Zr）组分改性胺化纳米木材，开发出一种制备条件温和、环境友好、可回收且高效的新型磷酸盐捕获纳米复合材料（PEI-PW@Zr）。Zr组分赋予PEI-PW@Zr捕获磷酸盐的能力，而多孔结构提供传质通道，从而实现优异的吸附效率。此外，该纳米复合材料即使经过十次吸附-解吸循环后仍保持超过80%的磷酸盐吸附效率，表明其可回收性和重复使用潜力。这种可压缩的纳米复合材料为高效除磷清洁剂的设计提供了新见解，并为基于生物质的复合材料功能化提供了潜在途径。
