Abstract

Despite the remarkable Cu(II) sorption biochar potential, it is challenging to desorb them for repeated biochar usage. The present study aims to develop engineered biochar by polarizing Ascophyllum nodosum (seaweed) biomass and magnetizing it with Fe₃O₄ nanoparticles coating. SEM, EDX, XRD, BET, and FT-IR helped to characterize engineered biochar. Unlike conventional, magnetite biochar exhibited a significant Cu(II) removal potential from an aqueous solution at pH 5. The native and magnetic biochar removal efficiency was 75.2 % (36.99 mgg⁻¹) and 90.27% (45.13 mgg⁻¹), respectively. No significant change in temperature effect was observed. Adsorption study showed that magnetic biochar followed the Langmuir isotherm model with Q_max 53.19 mgg⁻¹. Adsorption kinetics study indicates that magnetic biochar chemisorption dominates over physisorption. Thus, this study shows that seaweed-derived modified biochar could be the best alternative bioresource for removing heavy metals from wastewater. It can be reused to reduce the overall treatment cost of the process.
