β-FeOOH Modified Sludge Biochar as Efficient Adsorbent for Phosphate Removal
文献摘要：
β-FeOOH modified sludge biochar ( FSBC) was prepared and investigated in this work to remove phosphate from water via adsorption. FSBC exhibited superior adsorption performance for phosphate with the maximum adsorption amount of 27.17 mg/g at 25 ℃. The specific adsorption capacity of FSBC was 57.8％higher than that of commercial activated carbon at pH 5 with the initial phosphate concentration of 10 mg/L. Coexisting anions can inhibit the adsorption of phosphate, but cations (Cr(VI) and Cd2+) exhibited some promotion effect. The results of kinetic and isotherm models and characterization analysis in combination indicated chemical adsorption, as electrostatic interaction, metal phosphate precipitation and hydrogen bonding may be the dominant process. The adsorption of phosphate onto FSBC was a monolayer adsorption, and the process was endothermic. After four adsorption/desorption cycles, the adsorption capacity of FSBC for phosphate decreased by 36.4％, which was in a distinct comparison with the 57.5％ of SBC.
