Complex phosphate adsorbent, denoted as LaFe-activated carbon fiber (LaFe-ACF), was prepared from lanthanum, iron and activated carbon fiber using a liquid phase deposition method. Single factors such as Fe/La ratio and total concentration of metal ions were discussed. The results show that the best Fe/La ratio is 3∶7, and the best concentration of metal ion solution is 0.15 mol/L. The phosphorus removal performance of LaFe-ACF was investigated in static and dynamic adsorption experiments. The isothermal adsorption study of the LaFe-ACF showed that Langmuir isotherm fit the experimental data quite well, indicating that the adsorption process was mainly through single-molecule chemisorption on the surface, and the maximum adsorption capacity was 29.44 mg/g.
