ABSTRACT = {In this study, the magnetic wakame biochar/Ni composites were prepared with three activating reagents of
H<sub>3</sub>PO<sub>4</sub>, ZnCl<sub>2</sub> and KOH by one-step pyrolysis activation, characterized by BET, SEM, TEM, FI-IR, XRD, Raman,
and elemental analyzer, and their adsorption performance for diesel were also analyzed. The results showed that
wakame biochar/Ni composites had larger specific surface area, abundant porous structure, and various reactive
groups, rendering its enhancement of adsorption efficiency. The adsorption experiments indicated that the maximum adsorption capacities for diesel using WBPA 0.5, WBHZ 0.5 and WBPH 0.5 were 4.11, 8.83, and 13.47 g/g,
respectively. The Langmuir model was more suitable for the adsorption isotherms process, and the Pseudo-second-order model could better describe the adsorption kinetic experimental. And the magnetic wakame
biochar/Ni composites presented good stability and recyclability. This study provides a novel pattern for the
high-value utilization of wakame, having huge potential in the treatment of oily wastewater.},
