Cover Story: The commonly used two-step and one-pot synthesis methods for producing biochar require the use of iron salt solutions, resulting in the undesirable consequences of energy consumption for dewatering and potential pollution risks. To address this drawback, a magnetic sewage sludge-derived biochar (MSBC-2) was synthesized by a solvent-free method in this study. The maximum adsorption capacities were 151.52 mg·g−1 for Pb2+, 109.89 mg·g−1 for Cd2+, and 74.07 mg·g−1 for Cu2+. Surface complexation, cation–π interaction, ion exchange, and electrostatic attraction mechanisms were involved in the adsorption of Pb2+, Cd2+ and Cu2+ onto MSBC-2. Overall, this study will provide a new perspective for the synthesis of magnetic biochar; MSBC-2 shows great potential as an adsorbent for heavy metal removal.
