Abstract An adsorbent material (LB/PPy) with specific adsorption of anions was prepared by modifying reed-bottom biochar (LB) with polypyrrole (PPy) and achieving efficient removal of fluoride ions from water bodies. The LB/PPy material was structurally characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), pore size analyzer (BET), and Fourier infrared spectroscopy (FTIR), and the adsorption kinetics and key influencing factors of LB/PPy on fluoride ions were investigated by batch adsorption experiments, which revealed the specific adsorption mechanism of the material on fluoride ions. PPy increased the adsorption kinetics of LB/PPy on fluoride ions by the quasi-secondary kinetic model, the adsorption process has both physical and chemical adsorption, but mainly chemical bonding. The maximum adsorption capacity was 45.34mg/g at 40℃. The adsorption capacity increased with the increasing temperature. The optimum pH value of this material was from 8 to 10 to remove fluoride ions. It could ensure the good specific adsorption capacity of fluoride ions in the presence of multiple ions, which has a high application value.
