This work develops Fe–Ni particles loaded on biochar (Fe–Ni/BC) to remove U(VI) efficiently. bimetallic (BC) can improve stability and reactivity, the mesoporous structure of BC effectively reduce Fe0 aggregation. The removal ability Fe–Ni/BC is higher than that Fe–Ni, BC, Fe/BC. With aid kinetics isotherms, data were fitted by pseudo-second-order kinetic model (R2 ≥ 0.999) Langmuir 0.94). Meanwhile, exhibited largest capacity 250.78 mg/g for at pH 5.0 a temperature 303 K. Removing uranium using was carried out in following steps: First, solution sorbed onto surface through chemical bonds. Second, Fe(II) contributed reduction process. At same time, formed primary cell underwent electron transfer. Moreover, Ni0 adsorbed H2 generated corrosion, forming Ni–H prevent agglomeration U(VI). results indicate enhance sorption-reduction synergistic effect. offers valuable insights into design nanomaterials environmental remediation contamination.
