	abstract = {Excess phosphorus (P) in water can lead to eutrophication and upset ecological balance. In this study, biochar with ultrathin two-dimensional nanosheets from the natural mesocarp of shaddock was chosen as the carrier. The highly dispersed and small particle size of La(OH)3\&nbsp;on the surface of the nanosheets (MSBL3) was successfully achieved using chemical impregnation for the adsorption of P in aqueous solution, and the maximum adsorption capacity was 260.0\&nbsp;mg P g-1\&nbsp;[La]. The differences in surface crystallization of La(OH)3\&nbsp;on biochar at different La loadings were analyzed using the high-precision characterization methods. After six adsorption{\textendash}desorption cycles, MSBL3 retained 76.7\% of its initial performance in terms of the P adsorption capacity. The preparation of 1\&nbsp;g of MSBL3 costs about RMB 1, and it\&nbsp;could reduce the P concentration in 2.6 ton of\&nbsp;Laoyu River\&nbsp;water to below the eutrophication threshold; and the inhibitory effect of MSBL3 on the eutrophication of water bodies was confirmed by the growth state of water hyacinth. Furthermore, 0.1\&nbsp;M MSBL3\&nbsp;could inhibit\&nbsp;Escherichia coli\&nbsp;and\&nbsp;Staphylococcus aureus\&nbsp;up to 98.7\% and 85.0\%, respectively, which indicates that MSBL3 can be used to recover P from water and also to improve water quality. In addition, the growth of the maize seedlings verified that the P-absorbed MSBL3 waste is a good soil fertilizer and can solve the problem of post-treatment of the adsorbent. In conclusion, MSBL3 prepared in this study is a promising P sorbent for application.},
