Synergistic adsorption of heavy metals by magnetic composite biochar: Performance and mechanisms in co‑contamination systems
This study demonstrates that a magnetic composite biochar (M-AMK) fabricated via grinding-assisted pyrolysis and hydrothermal methods effectively and selectively removes lead and tetracycline from co-contaminated water through synergistic mechanisms including ion exchange, surface complexation, and the formation of stable TC–Pb complexes.
