Novel lanthanum doped biochars derived from lignocellulosic wastes for efficient phosphate removal and regeneration
Original language description
Phosphorus reduction from wastewater is vital to mitigate eutrophication of receiving waters. In this study, discarded lignocellulose biochar loaded with lanthanum defined as La biochar was applied for phosphate adsorption. Based on the design of response surface methodology, La biochar displayed a high phosphate adsorption capacity of 36,06 mg P per g, strong pH compatibility from 3 to 12, favorable selectivity for phosphate among foreign ions Cl, SO42, CO32, HCO3 and NO3, excellent reusability with 92,3 percentage desorption efficiency and retained 85 percentage adsorption capacity after five recycles. The adsorption law of La-biochar perfectly matched with the pseudo-second-order model and the Langmuir model. Moreover, real wastewater adsorption experiments indicated the removal of total phosphorus within 20 min. Ligand exchange, electrostatic attraction, and complexation mechanisms contributed to phosphate adsorption on La biochar. Overall, the La biochar material could be applied as a potential
