Abstract Modified Rice straw biochars were used as absorbents to remove Sb(Ⅲ) from water. Rice straw biochars modified by Mn and Fe-Mn were marked as Mn-BC, Fe-Mn-BC respectively. Firstly, the surface properties of the adsorbents were analyzed by BET and SEM. Secondly, under the conditions of the optimal pH and solid-liquid ratio for adsorption, experiments of isothermal adsorption, kinetic adsorption and coexisting anions in the system were carried out. Thirdly, the regeneration adsorption capacities of modified biochars were investigated. Finally, FT-IR、XPS were used to explore the adsorption mechanisms of Sb(Ⅲ) on Mn-BC and Fe-Mn-BC. The modified biochar had larger specific surface areas and total pore volumes than BC. Under the condition of the optimal pH 2 for BC, pH 4for Mn-BC and Fe-Mn-BC, the optimal solid-liquid ratio 2.5g/L, and at 25℃, the maximum theoretical adsorption capacities of BC, Mn-BC and Fe-Mn-BC were 5.08, 11.45, 29.45mg/g respectively, The adsorption of Sb(Ⅲ) by BC was highly related to physical adsorption, and the adsorption of Sb(Ⅲ) on Mn-BC and Fe-Mn-BC were related to chemical and physical adsorption. The adsorption of Sb(Ⅲ) on Mn-BC was greatly affected by F-, HCO3- and H2PO4-, and the adsorption of Sb(Ⅲ) on Fe-Mn-BC was nearly not interfered by ion type and ionic strength. Compared with Mn-BC, Fe-Mn-BC had a greater adsorption and regeneration capacity. The adsorption mechanism of Sb(Ⅲ) on Mn-BC and Fe-Mn-BC would be described as follow: firstly, most of Sb(Ⅲ) was oxidized to Sb(Ⅴ), then Sb(Ⅴ) was combined with Mn of Mn-BC or Fe/Mn of Fe-Mn-BC to produce relatively stable inner layer composites Mn-O-Sb and Fe-O-Sb-Mn, through the obvious electrostatic effect under acidic conditions. In addition, the functional groups —OH, C=O, and —NH of modified biochar also played an important role in adsorption
