Synthesis of Lignin-Derived Hierarchical Porous Carbon via Hydrothermal-Phosphoric Acid Synergistic Activation for Enhanced Adsorption of Tetracycline.

ABSTRACT: Tetracycline is a low-cost broad-spectrum antibiotic and widely used in medicine and aquaculture. Its residues are usually released into the environment through wastewater, which may lead to the spread of antibiotic resistance genes and pose ecological risks. To address this environmental issue, a hierarchical lignin-derived porous carbon (LPHC) was synthesized using renewable biomass lignin as the precursor through a combined phosphoric acid-activated hydrothermal pretreatment. The resulting LPHC was used to effectively remove tetracycline from aqueous solutions. Characterization results indicated that LPHC had a high specific surface area (1157.25 m²·g^-1), a well-developed micro-mesoporous structure, and abundant surface oxygen-containing functional groups, which en
