Abstract Phosphorus removal by phosphorus adsorbent is a common way to remove phosphorus from water. Compared with other phosphorus adsorbents, lanthanum-based phosphorus binders have the advantages of strong phosphorus affinity, wide pH adaptability, and environmental friendliness. Among the lanthanum-based phosphorus binders, lanthanum hydroxide has high lanthanum content, and hence, greater phospho-rus removal potential. In this study, nano-lanthanum hydroxide was prepared by precipitation method for phosphorus removal in water. Through orthogonal test, the optimum preparation conditions were obtained as 1-hour reaction at 80 ℃ and a LaCl₃ solution of 0.12 mol·L^-1. It was observed by transmission electron microscopy that the prepared nano-lanthanum hydroxide was nanorods with lengths of about 65 nm and diameters of 5.8 nm. The experimental results showed that nano-lanthanum hydroxide could effectively adsorb phosphorus in solution in a wide pH range (1—7), and the temperature rise was conducive to the phosphorus adsorption process. At 310 K and pH=3, the phosphorus adsorption capacity of nano-lanthanum hydroxide could reach 131.11 mg·g^-1. The phosphorus adsorption process of nano-lanthanum hydroxide conforms to the pseudo-second-order kinetic model and Freundlich isothermal equation. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) showed that the mechanism of nano-lanthanum hydroxide phosphorus removal included dissolution precipitation, electrostatic adsorption and ligand exchange between phosphate and OH^- in nano-lanthanum hydroxide to form stable inner sphere complexes.
